non-service provider doing what small companies do when their in trouble

Cell C is a small company in financial trouble using Failed Debit Order Penalty Fees to collect revenue. Change Your debit order date, they'll still use the old date despite telling you the date is changed. Make a payment arrangement, they'll still try and debit your account. If an account is closed, the error message returned will confirm such, but Cell C are not bothered. They will attempt to collect from same closed account perpetually to generate as much R70 charges as possible. They will never ever respond to a single email no matter how many you send. Once in a while, they might call you after hours from an 087... number (probably hoping you do not respond, so they do not have to do anything) even then that call will only be for you to repeat the obvious and for them to tell you that they will escalate the matter. I have managed to pay off my 24-month obligations. I am now left with a balance of R140 worth of charges they refuse to take responsibility for and that I have no doubt they will make every effort to make it R210 next month and R280 the month after that. A game which they will play by themselves from here on in.
