NEVER ENDING CONTRACT AND EVER FULL MAILBOX

I bought a 2-year contact phone in January 2014, which means my contract expired in December 2015. I have tried to contact mtn telephonically to advise them to close this account, which still baffles me as to how their systems cannot alert them to expired contracts. <br> <br> The telephonic options are too limited, and there is no option to speak to a consultant anymore. So basically ones hits the wall everytime.<br> <br> Sending email has also proved useless as I always got an auto response that the email box is full. Now they have charged me R515 for a contract that was supposed to cost R199. By the way, mtn revised this contract upwards by R10 in the middle of the contract.<br> <br> MTN, CAN YOU PLEASE STOP THIS ACCOUNT! IT GAS EXPIRED!
