Worst Service I ever received

My data account for 31/3/15 was over R2 000. For 11 months my account was R99. I did not pay the account because I want to work through a detailed billing to see where and when so much data was used that caused out of bundle usage. According to me I did not do anything different from the previous months. From 31/3 to 29/4 I was phoning Autopage trying to get a detailed billing. If I used so much data I will pay the account. I have proof that I spend 2h30min (13 phone calls) on the phone with several members of Autopage trying to get a detailed billing. On 20 April nothing was sorted out and after 46:39min (holding on for most of the time)on the phone the answer the lady gave me was they request a detailed billing. I lost it because that was the 3rd or 4th time a request for a detailed billing was send. I myself fax a request through on 31 March. I asked again to speak to a supervisor and after no supervisor was available I ask the lady to inform a supervisor to phone me. No one phoned me up until now. My account for 30/4 was also high but I paid the R734. On 29/4 I phoned again to speak to a supervisor without success. My line is still suspended without anything sorted out
