MTN Contracts

My contract account has been deactivated due to non-payment. I have made payment and it's been over 2 months and I haven't been reactivated. I have emailed (it has bee escalated over and over), I have messaged them on FB and I have called. I get put on hold, when someone finally picks up they say my contract was on the old system and they put me back on hold until they eventually drop.

I want to be reactivated, I don't know what's so difficult about that...
