Data billing

I am not happy. In December Mtn billed me for data, which was not used by me on my cell ***. After the holidays on 05 January 2016 I started at the branch and after 5 visits to the branch and 6 calls to the call centre I was informed on 27 January 2016 that my account will be reimbursed with R 3774,65 within 30 days. So on 25 February 2016 I called again to enquire on the status and if everything is still in place for reimbur*****t on 27 February 2016. The latest now is that it will only reflect on their system after 30 days and then the process will start to reimburse me , which can take another 5 working days.<br> <br> The cell no applicable is *** (my minor sons cell) and the last query no was ***<br> <br> Please help<br> <br> Thank you <br> <br> Tai Theron
