Data and airtime depleted with no explanation

I have tried numerous times to resolve this issue with cell c via consultants however they proved to be of no assistance. Firstly I recharged my account with R600 and bought monthly data as usual however my account was not updated with the data as the data balance as per *101# balance check and *147# balance check and both indicated as 0.00 balance on my account which is odd especially after loading airtime and buying data immediately. These options are supposed to assist us as customer to manage airtime and data which is not the case. I called the consultant to check up on this problem the response I got was that I am supposed to use *101# balance query option, the consultant transferred me to service rating before I could even ask further questions. I loaded further R300 Friday and proceeded to load data again and same thing happened and all of a sudden I get an SMS indicating that my data is depleted and will be charged 66c per MB. I haven't had any feedback even after logging my query with them in two occasions ***- they gave me the same reference number for the two queries). Every time call them they say it's going to be resolved in 24 hrs to 48 hrs and, they just don
