Telkom Mobile disregarded request for contract cancellation after expiry and have re-billed me instead of honoring instruction to migrate to pre-paid

Hi Zulu and the Telkom Mobile team

I asked for my 1GB tablet contract to be cancelled from Nov 2017 onwards as the 24 month contract I took out in Oct 2015 expired by the end of last month and I want to go to pre-paid but I am still being billed for this service (see Nov Bill attached).

Please honor my request for subscription SmartInternet-1GB Deal on ********** 508 at R 59 to be terminated and moved into pre-paid as I had already sent the cancellation form to you (see re-attached).

This request for cancellation was sent on 7 September 2017, so I require November's ******* debit order on this account to be refunded immediately and for my number to go on pre-paid as instructed - I have everything on record.
