Vodacom does not understand my complaint

Vodacom responded to my complaint on hellopeter (11 May 2018) saying a consultant will call me. None did. I did get an sms though saying that they will not give me my itemized bill for last month until I pay. They have completely misunderstood my complaint on 11 May. Vodacom did not send my itemised bills for April when they should have ( I pay for itemised billing) and they are demanding money for the month of April without showing me how they got to the value.
