Shocking bill

I regret signing a contract with you people, cause for the past year I have been fighting with you cause of your foolish behavior . You know nothing about being professional and respecting your customers. I called and spoke to one of your agents today wanting to know why my debt order was over R900 and the guy said it's an error from your side which couldn't be fixed on time. Mind you I got an sms on the 4th of October about this error, so all this time it couldn't be fixed?? Even worse you choose to debit me on the 16th where else our agreement is that I should be debited on the 15th of each month. Then again if I cancel the debit order and pay via EFT you ****en *****'s suspend my line and give me pathetic reasons. The agent advised me that you won't debit from my account next month but guess what, I don't ducken trust you cause you people are abusive and have broken so many promises. You better get back to me before end of business. I'm sick of you people.
