CELL C *****ING AIRTIME

I have been with Cell C a while now but recently it's become patient. This morning in less then a minute almost R20 airtime just vanished and the funny part was at this time my phone was busy rebooting. When I phoned the call centre the person I spoke to was telling me how I'm not on the right plan and that plan uses alot data. Not allowing me to once speak and explain that my phone was off, I rebooted it. Pathetic customer service. I have worked in a call centre since I left school, I know the script, I know the training. Not once did think of stopping to listen to what I am saying and even try and investigate.
