Ridiculously bad Service.!!!

I bought R300 of CellC airtime last week Wednesday that I haven't received. Called Cell C a few times when they eventually said I must call Standard Bank to reverse the money because they can't assist me. How is this possible? You can take money and data but when it comes to delivering a service you can't assist????

This is probably one of the most useless services I EVER received in my life, and I wonder why am I still a client at Standard Bank or Cell C. This is seriously ridiculous!!
