Cell C Negligence

Cell C cannot change a debit order date to the 1st of the month, after numerous attempts, they still haven't done it, now I'm sitting with an issue where they messed up with a double deduction, now after numerous phone calls and a mail that I am paid up, they want to cut off my service because of the useless customer service agents that cannot allocate the payment and now my credit score is in the balance because of them, atrocious service! Will never recommend them to anyone, moving to another operator as soon as my contract is finished.
