Cell C Useless Customer Service

Asked for the Team leader, after beeing transfered 8 times all times been sent to the rate our service speech , after that the call ends, I eventually got through to Iyanda. He tried to help me but kept saying they see no deductions on their side. He said he would phone me Monday 10am. HE DID NOT call back Monday. I called back 2pm again the consultant was very unhelpful and would not let me speak to the team leader Iyanda, i would then get transferred and again after being on the phone for an hour of getting rate our service and then hung up on, I eventually got trough to Thani. He then gave me exactly the same speech and info as the previous Iyanda. He said he would call back that afternoon 4pm he did call back. He still could not solve the problem said I must wait a month so they can say what is wrong.that was unacceptable to wait a month , plus I must call them back, What kind of service is that. I then suggested to test the problem while he was on the phone. problem found. I am still waiting for a cal
