Infuriating service from MTN

<p> Had a data contract with MTN, what appaling service. My contract expired, i continued for some months with them but thye strated billing me ridiculous amounts. Cancelled the service but they continued to bill me. When i queried the bill nd requested an itimesed bill no one could help. Made a part payment in good faith that I am willing to pay as long as i know what is it that I am paying for. Queried with the shop, call centre and ultimately wrote numerous emails, I received a statement but no itemised billing. Then they had the audacity to hand me over, again i requested the itimised billing nothing. I need to know what is it that I am paying for to date no one could tell me. This is so uncalled for as i made it clear that I will pay as long as I know what is it for. MTN is unhelpful, bully and abuse its customers. I vowed that my family and I will never utilise their service ever again. </p> <p> </p>
