I have been phoning ever since I have made payment from the 16th April 2026 to get settlement letter and terminating the account now I am told I need to pay a cancelation fee which I was suppose to be told and it was suppose to be included on the settlement letter ,I cannot be told now that I need to pay for cancelation fee which I was not told off it I was also not included on the bill ,I need the account to be closed I have never ever experience a bad service like the in my entire life with MTN why was the fees hidden from me from the first place If I was aware I was going to pay that very same day .I need the account to closed You can also check my emails I was communicating with legal which they failed to assist me .I was not told that I will pay cancelation fee why was it not included because I want to settle and close the account mtn is such a disgrace shame from April phoning for assistance and no one is willing to help me ,all thier emails they don't respond even their complaints department .Big company but has poor service I just need the contract to be cancelled finish .
