wrongfully suspending my mobile line

On the 16th of March 2015 I made a payment of my contract number, after the payment was made few days later I received an sms saying I should pay, I ignored this since I knew that I made the payment a day later when it was due, I however continued receiving these sms's reminding me to pay. I thought I should contact the call center in order to solve this issue, I however waited for more than 30 minutes waiting for a consultant. I could not wait anymore I then sent an email to them and the response I recieved was automated and I couldn't understand it. They eventually suspended my line, then I called the call center again, at long last I got through to a consultant whom wasn't helpful at all<br> He just told me to get a proof of payment and send it them even though this payment was actually made at an mtn outlet. I followed his instructions, faxed through proof of payment, my line was still suspended, tried to call them (mtn contract dept) with no success.I waited and and waited to get through to a consultant until I couldn't wait anymore
