Unable to resolve billing query

<p>My debit order did not go off at the end of February so I did an EFT into MTN’s account a few days later and I’ve send them the proof of payment more than 3 times. I also cancelled the insurance and a data bundle on the same contract. They have suspended the number 3 times already, and currently it’s suspended again. No matter what I do they keep on saying I owe them money although I’m 100% sure I don’t. It’s impossible to speak to their credit or legal departments and they are refusing to phone me back to get this sorted once and for all!!!!! I am so sick and gatvol of this I don’t know what to do anymore!!! I’ve been fighting with them to get this sorted for 2 months now, but it seems impossible! I mean, you do expect bad service from MTN, but this is just absolutely pathetic!!! </p>
