Sick and tired of being **********

I loaded airtime advance of R10 and within a second (customer service says) I loaded another R10 airtime advance. When I went to check if the second airtime advance had loaded both of them were gone. It is nonsense that every time you complain about data with cellphone networks the problem is always your phone and never with them. I doesn't make sense that USSD can use data just because your phone uses 3G. When you want to log in a call you are told you cannot. When you ask for proof of their claim that your phone used data they refuse. This is ridiculous
