Cell C sucks

I have been a cell c customer for about 12 years. Good record, always make my payments, no problems etc etc. So i recently gave up contracts and only do prepaid. and somehow, when paying the last monthly payment for my top up contract, I apparently short paid with R52. They phone me and I apologoze and promise to pay immediately, which I tried, but by then they suspended the line already. So I phone th ecall center and they refuse to unlock my line, but I need to pay them from my cellphone banking app.... Anyway, go onto wifi ad make the payment, phone customer care again (from a diffirent phone because if you are suspended you cant even phone the call center). Now I think I will get my phone active again, after all, the complex where I live has a cell to gate system and I have by now been locked out for two days, relying on friendly neighbours to open for me. Lo an behold, they can not help me because one of hteir security questions is "What was your last recharge amount". Like I keep track of trivial things like that. So call after call the operator terminates the call because I do not pass the security check. You know, cause I am a ******** going around paying people's account in arrears. Diabolical!!! So, after 12 years of being a loyal customer, I now have to go to a shop with ID in hand proving that it is me before they can help me......but I am a prepaid customer, for now anyway.....so the Vodacom shop is just closer. *****ic Cell C!!!!!! This is the stupidest way to lose a customer
