Unbelievably Bad Service

I had an LTE contract with MTN which I cancelled in 2024. I called in in October to give notice of my cancellation and was given the reference number ***. The contract was to end on the 5th December but I noticed that the subsequent invoices still showed the LTE package. When I queried this, I was told that the cancellation didn’t go through but I must continue paying the full amount on the invoice to avoid my services being suspended. I have been calling MTN every month to get this issue sorted and to be reimbursed the money that I have been paying since this contract ended.

I learned this morning from a call centre agent that the contract cancellation was put through on the 30th of May, to end on the 30th of June. When I enquired about the credit note I was promised, she said that there’s no credit that will be coming to me because the contract is ending on the 30th of June.

I have not used the MTN LTE since December 2024 as I thought it had been terminated. Can you please assist in resolving this for me? I do not know where else to go.
