MTN poor service for cancelation.

I have been waiting from June 2021 when I had canceled and returned a device each month my account was debited I called and was told it is a process it will be canceled and I will be refunded. But each month went by I was still being debited and still being told the same thing the service from MTN was very poor. After 6 months of being debited and getting told the same thing and getting very bad service I have finally received confirmation from Dhanesh that cancelation has been done this is the first time I had proper information on what's happening with my cancelation. Now I just have to wait for my refund hopefully MTN does not take another 6 month's to process.
