Robbing The Common Man

I have recently moved over to Cell C on prepaid. I bought prepaid airtime which I loaded onto my phone & bought their wattsapp bundle. I checked my balance after buying the wattaspp bundle & saw there was R8 left over & I had received R50 bonus airtime on my phone. I only received 2 videos & 1 wattsapp message only to find out that all my airtime is finished. I contacted to call centre who advised me that no wattsapp bundle was bought yet I have a sms from Cell C verifying the bundle. The consultant promised me that my complain will be resolved with 48hrs, it's now gone 7 days & I have not received any call from Cell C. I then bought more airtime & bought another wattsapp bundle. I also put in R15 airtime. I still have data on my wattsapp bundle but my airtime is all finished. NO ONE FROM CELL C can give an answer as to how the airtime get finished even though I have a wattsapp bundle on my phone. Cell C is just robbing the common man on the street with their fancy adverti*****ts that they are the cheapest yet they are robbing the common man on the street. I am truly disgusted with their service & lack of communication as well as their untrained staff.
