Cell C ******* for Themselves

I have had a cell c contract now for years. I recently discovered that I can't afford payment and canceled my contract. I am not sure why I have a case number but I will be asked to repeat my problem on the matter over and over again. I got R1000 airtime on prepaid and now that the contract is canceled the airtime has been taken away, my this was due to me as I payed cash and I bought airtime my contract has stopped but I'm waiting for my money 10 days later. b But for them to not even make a call or an sms to inform you this is being done is too much to ask them. I asked if they could help in the 6th of November and then they gave me a excuse of a case number but it will be sorted out in 2working days, after all the calls I made and explained the same thing to them only now Monday was it escalated and now turnaround time is 48hours thank you for all the effort you put into this. My biggest issue is that companies need there payments to be paid before hand but they are willing to take my money and not answer their mistake
