MTN lost my trust.

Data contract changed without my approval and now signal is dead after they started investigation a week ago, I've been struggling with call centers (9 plus hours), make believe AI generated emails (7 sent) of promises to sort matter out and even the branch can't assist driving a 180 km. As I stay in a rural area. The explanation is my account is too old and not reflecting on their new system. They do however have no problem emailing my statements to pay my 3 account's dead on time even with one account not active for almost a month. Makes you wonder the longer you are a loyal customer the less anyone can assist you.
