MTN South Africa: ********* business practices

MTN South Africa must be the worst cell phone network service provider. My three year contract comes to an end in November this year. So I sent customer care an email requesting the cancellation giving the normal required month notice also requesting that the number be made prepaid. On Tuesday first October I called one three five and spoke with Dinolin Moonsamy at MTN requesting the cancellation. However Dinolin convinced me to renew my contract and offered me a sim promotion of five hundred minutes any network and fifteen gigs data. After credit approval I accepted. My sim was immediately loaded with the new contract minutes and gigs. I also received a return email (On Oct 1, 2024, at 12:10, customercare <***> wrote:

I immediately checked my balance and indeed the airtime and gigs were deleted with zero balances. I have made numerous phone calls to MTN customer care also sent email to retentions and customer since Dinolin assured me that should I experience any problems I can contact him. Well I made so many attempts since Wednesday second October to date but not even a response.
