Over charging

Good day<br> <br> I have looked a query with Cell C on the 24 Oct 2015 advising them that everytime I recharge when I check my balance to call my airtime balance is on zero , free min when I call a non Cell C no.<br> <br> If there is anybody that can help me plz its been weeks now and I refuse to load airtime as I cannot use it and the explanation I get every time I call in to query this is that it shows internet usage. Sad part is I am not even on the internet my phone is off and in my bag. When I explained that to the agent I was advised about my data usage. My background date is off and I only use whatsapp (R5 whatsapp bundle) and Facebook. <br> <br> I received a reference no and was advised that I will get an SMS to advise me that my query has been resolved. I am still waiting for the SMS.<br> <br> The ref no : ***<br> <br> Please Help!!!<br>
