WAITING FOR 6 MONTHS FOR A QUERY TO BE SOLVED

Before i left for overseas I phone one of the consultants, i needed to know what I need to do to block my phone to not get a high bill on my return, her response was that i could not do that and she did not explain what I had to do. I received an sms while overseas telling me that my acc was R1000 after only being there less than a week, I tried in vain to get hold of them but could not. My bill now has rocketed to R4000 and I hardly used it. I got desperate so turned it off. On my return I visited the HO and spoke to a consultant who told me that he needed to get the tape of the conversation I had with the consultant. He would then contact me which he never did. I phoned AGAIN and I was then told they would send the tape to the nearest Autopage. They never did, so I phoned AGAIN this time I was told that I was not able to see the tape. In the meantime they kept on debiting my acc. with the amount, I reversed it x 3. I emailed them asking to please send me a statement and to please contact with this query as it is urgent. I have still not heard a thing.My phone was then suspended, very inconvenient. IT IS NOW 5.5 months and still nothing.
