No value for money

I bought the weekly 2GB data but could only use a portion of it simply because it got forfeited on the basis that there was no network coverage for a good 3 days. I called in the call center on 6th May 2022 to plead with them so that I can be reimbursed my remaining data that I did not use and got forfeited because of their technical problems. Fine, the lady who assisted me promised that MTN will gladly replace my data within 24hours,I have been waiting ever since. To do a follow up on the 30th May 2022, I called in again and this time around was assisted by a male figure who claimed that my data was expired at the time of my request. I can afford my own data, what doesn't sit well with me is the fact that I cannot use it all due to network coverage.
