One year complaint not resolved!!!

I went to Brooklyn Autopage to query how to save my calendar events as my phone was broken and I needed assistance on how to back up my information. One of the consultants assisted me. This took 2 days, 3 and 4 February 2014. A week later I received a call from Autopage informing me that my internet usage(usage charge) was extremely high on these 2 days, bringing the account to R 3674.08.00 excl vat. I notified them that I had not gone on to the internet, but was assisted by their consultant then. The Johannesburg branch investigated the problem and came to the conclusion that it was the consultants fault, and they will rectify it. Ever since then, my phone has been cut off every 2 weeks, which leads me to call them constantly with no response(no answer). - this is extremely costly from my side!!! I leave voice messages every time and only receive call backs after 2 or 3 days, by which then only they activate my phone. Since then I have corresponded with Collen Appoulis ***) or his manager Melanie Dhaniparsath ***). The account has still not been sorted and once again my account has been suspended. Hallo Peter seems to be my last resort. FIX IT !!!!!
