Cell C "customer service"

I have 2 contracts with Cell C which I have a huge problem now. The contracts is for 2 of my daughters. 10 years ago I took out the contracts with other providers but as the economy was bad the contract went from one provider to the next. Eventually it was taken over by cell c. My daugters now pay for their own account although still on my namw. Phoning their "customer care" when you have a problem IS a problem. First they ask security questions and if one of the answers are not satisfactory they refuse to help you. I mean am I going to ***** a contract over the line???? We tried cancelling the one contract. What a mission. Customer care could not help. The outlets are not authorized, the cancellation number just kerps on ringing. Ok after struggling for 2 months we heard about extra costs to cancel. The other number we went in for an upgrade. There was nothing in arrears on my accounts. The called number was made prepaid. Suddenly they normal contact received an sms stating account was almost R2000 in arrears. Both nimbers was paid from the same account cash with each number on payment. I phoned "customer care". They could not help. Went to an outlet. The gentle man first said they cannot do anything. After me refusing to leave he took the proof of payments ( yes I have each payment) and mailed it. If I asked him a question he just stared at me with a blank look. He phoned someone, put the phone down and said it will take 48 hours. This was friday. Monday both of the numbers, even the prepaid, was blocked. Customer care again. After an hour the lady gave me her mail address. They refuse at any time to give me a direct mail or number for accounts or finance. I mailed all the proif. The lady let me know she received it and forwarded it. The lines was back on. I was supposed to get an update. No I must phone customer care, speak to someone new and find out myself what is going on. Got no further help. 3 weeks later (yesterday) the lines were blocked again. Phoning customer care again, explaining all again. I walked away with a reference number and a wrong mail address. Contacted them on the website yesterday evening, got another e-mail address where I must explain all again to a new person. Its been sent Through early this morning and updates are being promised but to no avail yet. I will not leave it and will be like a leach. The remainder of my contracts will be cancelled when it runs out. If anyone have or had a similar experience please contact me as I am fed up that things do not get resolved and I will take this matter further. Until now they do not want to give me any contact directly in finance or accounts. It takes me min 40 mins to explain this to every new person and most of the time the do not get it. Lines are still down even though I as the customer did nothing wrong
