Worst service ever. I would be ashamed if I was the CEO of cell c

Tried to change my banking details on two occasions. Operator did not do his job. My debit order did not go through. Not my fault. I received a msg saying my line will be suspended. I called and the oprator said I must reschedule my debit order which I did. Again they said it will be suspended. Finally spoke to someone again and I asked him when must I pay and will it be ok if the debit order is scheduled for the 25th. I asked clearly if this will be ok and that my line will not be suspended. Today 20.09.18. Get a sms the line will be suspended. Call cell c and they say that they cannot stop ghe suspension of my line. I said they must listen to the recording. Call me back. They said that on the recording the operator did advise me. I ask for the recording and I am told it is the property of cell c and that I cannot get the recording. How convenient is that for cell c? Worst service ever received. No customer service at all.
