Very disappointed in Telkom

I contacted Telkom around March advising that the SIM card on which they provide me with data is lost or ****** since January 2025 and that I do not have the benefit of the data, requested for the contract to be cancelled which was never done. I did not pay the account for April and May and Telkom handed me over to Nu Debt in May. I made the payment of R623.79 as per threatening letters from Nu Debt and forwarded the proof of payment which I still have.I went to the Telkom office in Menlyn shopping mall,spoke to a consultant who advised me that the contract is on a monthly basis and as soon as the payment is allocated the contract will be cancelled. I then also emailed the proof of payment to *** as requested by the consultant I spoke to at the telkom office via phone. I then received an email stating that it takes up to 17 days for a payment to be allocated and contract will then be cancelled. To my surprise Telkom debited my account again in June and are not responding on any of my emails. I am at a point of taking this matter up with the Ombudsman as I will be paying Telkom forever. I expect Telkom to cancel this contract as I am not going to pay them for June as well.
