CELL C IS RIPPING ME OFF!!!

It has recently comed to my attention that every time i recharge my account within a few hours my air time is gone.On the 20th I bought 100mb data at 06:02 am at 17:30 i bought R35 air time by 18:05 my air time balance was zero without making any calls. I called cell c and spoke to sbahle mhlungu from KZN who told me that the data I loaded was not credited to my account I asked to speak to a team leader and she hung up on me.I called them again and this time asked to speak to a team leader I spoke to a very rude team leader from the Johannesburg head office who said I had not bought the 100mb data he refused to help me out and told me there's nothing they will do to fix this issue. yesterday I bought R50 air time then with that air time I bought data for R19.00, I used wifi all day so the data was not used when I got home I had network issues so I couldn't use the internet to my horror at 2am I received an SMS telling me that my data was used up without even using it. 2 minutes later my R29 air time was gone. CELL C IS RIPPING ME OFF AND I WILL REPORT THEM TO THE OMBUDSMAN AFTER THIS HELO PETER COMPLAINT .
