Money making scheme, Pathetic and lack of customer service

I am honestly tired of Cell, I cannot wait to finish paying off their contracts so that I call it quits. I won't even advice anyone to take a contract with them. The following are incidents that incurred in the last 3 months and unfortunately I as the customer have to suffer financially. 1. Dylan sold me things I did not agree to and I had to pay for his stupid mistake. 2. I was handed over for a contract that I cancelled, complained about that no one bothered to get back to me . 3. Two of my contracts were not debited and there was money in my account and I have never stopped any cell c debit order from my bank and that has resulted in cell c charging me R70.00 for debit order that did not go through on each account. 4. I got the statement that says R626.98 is due by 25th Sep and when I called to find out I am told no don't worry only R348.99 will be debited when I request the new statement that reflects R348.99 I'm told sorry we can't send you updated statement for what I don't know. I honestly don't know what to do anymore , the sad thing is I have to suffer and pay for their mistakes.
