continues to debit my account!

Cell C have not only overcharged me for the last month of my contract but have also continued to debit my account!! <br> When calling in to find out what the story is regarding being overcharged, I was promised feedback which I didnt get, this was after being passed from person to person. All I want is an answer and definitely a refund regarding this months debit order. The consultant who cancelled the contract initially did not communicate any costs when asked.<br> Cell C you might be cheaper but definitely more expensive and frustrating in the end!!
