# Fibre Cancellation Notice Periods Explained Source: https://urbanx.co.za/knowledge-hub/switching-moving-managing-fibre-service/fibre-cancellation-notice-periods **Answer:** The notice period is the time between valid cancellation notice and the effective service end under the agreement or applicable law. It is not necessarily the same as the invoice date, line-release date or date the customer stops using the service. Submit notice through an accepted recorded channel and obtain written confirmation of every relevant date.

Notice-submission date The day the customer sends a valid instruction through a channel recognised by the provider. #### 2. Effective cancellation date The date the service agreement and ordinary access are scheduled to end. #### 3. Final billing date The invoice or account-closing date. The final bill may be produced after service ends and can include pro-rata adjustments, equipment charges or credits. #### 4. FNO line-release date The date the old ISP’s access association is ended or made available for a supported new order. It may align with cancellation, but the customer should not assume it has. These dates should be requested separately when another ISP is waiting for the line. ### Contract notice and statutory notice are not interchangeable A provider’s agreement may set an ordinary notice rule for month-to-month or end-of-term cancellation. It may use: - a stated number of calendar days; - a stated number of business days; - a full calendar month; - notice before a monthly cut-off; or - another clearly described calculation. Separately, section 14 of the Consumer Protection Act provides a 20-business-day recorded-notice cancellation mechanism for qualifying fixed-term consumer agreements within its scope. Amounts owed through the cancellation date and a reasonable cancellation penalty may still apply. The CPA provision is not a universal statement that every fibre service can be cancelled at no cost in 20 business days. Applicability depends on the customer, agreement and law. Obtain professional advice if a material dispute turns on legal interpretation. ### How to submit effective notice Read the agreement for the permitted channel. A useful cancellation notice contains: - account holder’s full name; - account or customer number; - service address; - circuit or line reference if known; - clear instruction to cancel; - requested effective date; - reason, only if required; - request for line release where another ISP will take over; - router-return enquiry; and - request for written acknowledgement and final-account details. Use email, portal ticket, form or another channel that produces durable evidence. A phone discussion alone is difficult to prove if the instruction is not recorded correctly. ### Ask the provider to confirm this exact list 1. Date notice was received and accepted. 2. Contractual or statutory basis used. 3. Effective service-end date. 4. Last ordinary subscription period charged. 5. Estimated final invoice date. 6. Any early-cancellation amount and its itemisation. 7. Router or equipment return obligations. 8. Expected FNO cancellation or release request date. 9. Account-closure confirmation method. If the agent gives only “your cancellation is processed,” ask for the dates. ### Calendar days, business days and calendar months These terms can produce different outcomes. - **Calendar days** count ordinary dates, usually including weekends and public holidays. - **Business days** exclude days defined as non-business days by the applicable law or agreement. - **Calendar month** may refer to a billing-cycle or end-of-month structure rather than a fixed count of days. Do not calculate a legal deadline from this guide. Ask the provider for its calculation in writing and compare it with the current agreement and law. ### What if notice crosses a billing date? The ISP may issue the next invoice because service remains active during the notice period. Whether the invoice is full, pro-rated or later credited depends on the billing model and agreement. Compare: - invoice service period; - cancellation effective date; - debit-order date; - any advance billing; - credits on the final account; and - new provider’s activation date. An invoice generated after notice is not by itself proof that cancellation failed. ### What if you change your mind? Ask immediately whether cancellation can be withdrawn. The ISP may already have submitted the FNO termination, scheduled a line release or closed access to a promotional package. Reversal is not guaranteed, and the customer may need a new order. Obtain a new written reference for the withdrawal rather than relying on an informal assurance. ### How cancellation affects switching For a same-FNO migration, ISPA recommends a coordinated process in which the old ISP gives the FNO the correct cancellation date before the new activation request proceeds. The new ISP should explain its supported workflow. Do not ask the old ISP to release the line immediately unless you accept that the service may stop before the gaining ISP can activate it. Do not leave cancellation until after the new order if the FNO requires the old association to end first. ### If the cancellation is not actioned Write to the provider with: - original notice and timestamp; - acknowledgement or ticket reference; - agreed effective date; - later invoices or debit records; - follow-up correspondence; and - the remedy requested. Request correction of the account, confirmation of line status and a final statement.

Ask the provider to show the clause and calculate the effective date. **Can an ISP bill during the notice period?** Yes, service and contractual charges can continue until the effective end date. Dispute charges that fall outside the agreed period with evidence. **Does cancelling with the ISP release the line immediately?** Not necessarily. Ask when the ISP will terminate its FNO access service and when the line should become available. **Is 20 business days always the cancellation period?** No. Section 14’s mechanism applies to qualifying fixed-term consumer agreements within its scope and does not remove valid amounts or reasonable penalties. **Should I stop the debit order after sending notice?** Do not treat a payment stop as cancellation. Confirm final amounts, dispute errors formally and manage payment instructions carefully to avoid unintended arrears.
