LTE contract not being cancelled

<p>I have submitted my cancellation form to Telkom start of January explaining that I have migrated to Telkom Fibre and want to cancel my LTE contract. I told them that I havent used any of the LTE data because I have had Fibre since Decemember, so I dont want to be invoiced for January. They emailed me back assuring that my contract was migrated to prepaid and I would no longer be billed. When I checked my LTE account beginning of FEB I see I was awarded with data again which shouldnt have happend as I should be on prepaid. I contacted Telkom Mobile and spoke to a lady who requested the the Telkom letter from me via email. I have sent her the email and she said she couldnt assist me she would execulate the matter to her manager. It has been one week and the manager hasnt made contact with me. I have emailed her 3 times to request feedback and im getting no response from her. Telkom has issued me an invoice for January even though I havnt used any of the data and my contract is still running.</p>
