3 months and bill still incorrect.

I have desperately been trying to resolve my bill with MTN, to absolutely no avail. First I am billed for packages which I don't have, then I am not billed for what I do have. I have been unable to view any online invoices to verify the charges either. Call centre staff and supervisors promise to send me the invoices, which of course never happens. No one ever responds to the countless emails I have sent either. I have even lodged two separate complaints, neither of which has been responded to. Rajesh (supervisor) even greets me by my first name, that is how often I have called in to attempt to have this resolved. So please tell me, what more am I supposed to do? Should I take my tent and camp out at your offices until someone acknowledges my valid complaints? I would beg some more for someone to at least call me, but I know it is futile. It's almost as if MTN cannot make any outgoing calls of their own.
