over charge on contracr

Hi,<br> <br> Apparently I have been getting 3 gigs of extra data per month that was discounted 100% since the start of my renewal contract in may this year until now. Now I am being charged 100% making my phone bill about R 200.00 more than usual.<br> <br> So I call in and spending 20 minutes explaining my situation. Keep in my I did not agree to these 3 extra gigs and always thought that it was carry overs from the previous month which is what my previous congratulations used to do. The person that helped me was very helpful and explained to me that she well get the amount discounted again. This was 2 weeks ago.<br> <br> I called in yesterday again with my reference and got told something completely different that the 3 gigs were discounted only for 4 months. Keep in mind I am completely unaware of this discounted 3 gigs. I told the person helping me that if this money gets debited off my account there will be problems and that I did not apply for said 3 gigs and it is not my problem that it was put on my account. The lady said she would put a manager or accounts person in contact with me. This has not happened yet and the full amount was debited off my account. <br> <br> You are to reimburse me that money.
