Horrible experience with telesales

I have been **** to by a telesales agent at mtn in February 2022. I was on a package that gave me 1000 minutes and 50gigs of data for 499. The call center guy told me that I was paying too much and that I should rather upgrade to this new amazing deal where I pay 279 and get 80 gigs of data and everything will remain the same. I confirmed ... so my minutes will stay the same and he repeatedly **** to me saying it will. When the package kicked in the next month I was only given only the data and all my minutes were taken away. I thereafter repeatedly called mtn to fix and they have not done anything. I spoke to the following people on various dates as below. It's really frustrating in a world where technology is advancing and people try to trust over the phone sales they still let you down. This is false advertising and is not in line with treating customers fairly.
