mtn poor service

Its been 8 days and mtn as not resolved the ***** upgrade on my contract. Alice van der merver ref *** says i must now go to a police station for an affidavit. while she sits in her comfortable office. why dont you show me proof that i went and did an upgrade. the other thing is that this is a work phone i use internet and my calls everyday, i asked the assistant at gateway mtn what happens because i am using my phone for work and this airtime and data that is not mine is being used, he has the damn cheek to say i will have to pay for it. you'll are quick to take people s money, but useless to sort a problem. Is this how mtn works yourl make peoples lives difficult and in so much inconvenience. I just cnt wait for this pathetic mtn contract to end. I will never advice any of my freinds or family to join mtn, they wil regret it for the rest of their lives.
