Poor service from MTN

I got two contracts with MTN, the one for data and another one for my cell phone. The data one, I got in 2021, it was on the 17th I just don't remeber the month. They were loading 80GB every month and it would last me the whole month. From Last year, it started getting depleted after 5 days if it was longer, it would be 10 days. I sent out emails to MTN regarding the matter and they would respod with background data and apps. I was not satisfied with their answers and kept going back to them, but the same answer would be written to me. I eventually cancelled the contract last year.

My phone contract was taken on the 1st of Dec 2022. But after cancelling the contract, they moved my debit date to the 17th of every month. Not even once have a asked for that date. I called them to change the date, they moved it to the 1st of every month. but it has been two months that they have not been deducting on the 1st. I tried callling them a number of times, I emailed them, now I am getting ignored.

I handed these issues to the ombudsman who hasn't responded to me as well.

I am trully disappointed with their service, as they are ruining my credit score. Even today, I called to ask why they have not debited any money and they said they did not get the funds, that time, my account has money. I have not received an email from the bank to show that they tried debiting.

I am so defeated because they are not helpful, they do not come up with solutions to assist me as their client.
