Disgusting service

I've got two lines with Cell C, which are debited off of my bank account every 27th of the month. For some reason on the 27th of January the payment was not debited. I didn't receive notification of this, and thought there must have been some problem with the system. <br> Today, 3rd of February I get an SMS from Cell C saying that I am in arrears with them and that my lines have been suspended. The msg also stated that I will be charged a fee because of the returned debit order.I then contacted the \CUSTOMER SERVICE\" centre, where I was NOT assisted in a very competitive manner. I was told that it is my banks fault, as they said that there were insufficient funds in the acc. I then contacted my bank to see what the problem was as I am quite sure that there are funds available in my account. My bank checked my statements and said that cell c reversed the debit order, and that there was never a msg sent out saying that there we no funds in my acc. HOWEVER, none of this is my fault - but the 3 customer service agents I spoke to insisted that it was my own problem and were very rude and unhelpful. They all had the same bad attitude and tone. I am very unhappy & regret having this account."
