Poor Service

On 27/8 I received an sms from Vodacom stating that my data usage are extremely high and above my normal use. I contact 082155 on 28/08. Agreed to have the line immediately suspended for further investigation. I was promised to receive feedback in 3 working days. On 14/09 I called again because I have not received any feedback. I was told that it takes 15 working days and will be ready on 17/09. On 22/09 I called again and the assistant could not even open my request on the system. What terrible service. I need my itemised billing report asap in order for me to see when this line was used and if it was in fact myself. If I have not received an answer by 23/09 I will contact the ombudsman and lay an official complain.
