Account suspended!!

<br> I am a long time customer of MTN and am already on my 4th upgrade.<br> <br> I upgraded my account in April 2015 to a R550 per month contract and was not informed that my new top-up package was no LONGER a top-up package but now had a credit limit of R4476. So I was shocked when I started to receive enormous bills of R939, R1578 and R2071 respectively. I removed the credit limit and agreed to pay off the amounts but the debit orders MTN keeps trying to put through do no MATCH any of the statements they send to me. One month they decide to debit R71 (call centre agent said this was my fault!) and the next is R3201, which I reversed, and I asked for clarification from the call centre. Now my account has been suspended , still no clarification. MTN I need to understand what I am paying for before I pay. Your invoices and statements don't agree! WHAT IS GOING ON THERE???<br> <br> Now when I call the call centre (808) it tells me my cellphone number is an invalid MTN contract!!! I need to talk to somebody asap...<br> <br>
