WHAT THE HELL IS GOING ON WITH MTN???

I signed a contract with MTN in November 2014 for a monthly payment of +/- R500, i had a current contract with them for R330. so every month i paid my R900 for my two contracts, March 2015, my running contract was to expire, so i requested for it to be canceled. That was only done in June 2015. but i paid it, until June, fighting for it to be canceled, or switched to prepaid, whatever. <br> Suddenly i get a statement stating my outstanding balance of R5000? WHAT!!! After my mild heart attack, i tried to contact MTN (808), no response... for two month now...now response, they just do not answer. <br> So yesterday i pay R1000, even though i should only be paying R500, for my cell phone contract, and this morning i wake up, and my line has been disconnected, after the proof of payment was sent to them yesterday after making payment. <br> I have requested statements to be sent to me, with no avail. Today i phone the call centre only to hear it has been closed...so where do we go now for help? This is pathetic. i have been a MTN Customer for 10 years and this is what i get? pathetic!!! <br> No statement, no explanation, no line, no communication... dissapointed MTN.... get your act together!!!!
