incorrectly billed for 4 months to date!!

I have been trying to get my account sorted out for over 8 weeks now after nr.1 - MTN didn't do my upgrade correctly, nr.2 - they didn't provide me with my bundles as per the upgrade I signed, and nr.3 - they have been billing me incorrectly.<br> After numerous phone calls and visits to branches every time I get the response \this has been logged"and yet 8 weeks further we are still no closer to a resolution.<br> I don't know how you can call yourself a \""service provider\""....they only thing you are providing me with at this point is an irritation!<br> You are more than happy to debit my account and take my money (incorrectly) but take ages to fix the problem that you created...<br> After I spoke to your billing dept today they said a supervisor would call me back in 1 hour....we are no 3 hours later and still nothing!!!!<br> I am pretty sure this is now starting to border on infringing on the consumer protection act.<br> I need to someone in a management position"
