Customer Service Nightmare!!!!

I have never in my life had this poor service from any ompany. I arrived back from overseas last week and my line was supended, I then contacted the customer support centre and they said nothing was wrong and they reconnected. I honed you customer support at least 10 times after that to find out why this happened and they told me I have not paid my account. I was them told I need to go to a cell c store to sort this out, I went to Rosebank cell c and they told me they need bank statements. I supp**** this and they assured me everything is fine now. My account is on a debit order but they could find no trace of this. Yesterday at 6 pm my account was suspended AGAIN. I called customer support again and they told me the same story and reconnected. I have always paid by debit order but you have no record of this? This makes no sense. Just suspending my line without even letting me know. Great service Cell C!!! This will be my last month with you guys! Its your mistake that you cant find my previous payments!! Disgrace for a company that is in such financial trouble!
