No airtime loaded, no feedback from cell c

I bought R5 airtime twice on Sunday (via FNB mobile banking), both times I got the sms notification that I had successfully recharged. But alas, there was still no airtime loaded. I called the call center and was informed that Cell C was experiencing issues with airtime being loaded via banking channels. I called a further 2 times and it has now been 48 hours and I still don't have my airtime. The money has come off my FNB account. There has been no communication from Cell C. I had to buy emergency airtime yesterday as I desperately needed to make a call. So obviously there are other ways of sending airtime which Cell C has not bothered to do, for customers experiencing this issue. I have been with Cell C for over 12 years, but I guess its time to move on.
