CONTRACT DATA BENEFITS

I upgraded my contract around May and part of the package was getting 500 MB of Data every month. After few months not getting the full 500 MB, I logged an incident with Telkom call center. On the 31 August 2015 I got an sms saying my case number ***2 has been attended to and then given a Ref No: 502224. <br> <br> After a two weeks I called trying to find out the status of the case and I was told that my case is still being attended to and would be called back in a day or two. After a week I called again to inquire and one of the consultant took my details and promised that I would be called by the supervisor the same day. On the 5th October i called again and spoke to a certain lady and explained my issue, she then put me on hold to look for the supervisor and she came back saying they are busy and would send him/her an email. I asked to be copied on that email and she agreed but the email never came. I called again on the 7th and i was told the supervisor will call me back and I'm still waiting. Can someone please help as i have now lost patience with them and don't know what to do next. <br>
