Billing Chaos

My bill varies between R1500 and R6000 from month to month. I am being overbilled, that after we capture our meter reading online every month. I keep track and there is no such variation is usage. The answer is simple, you are OVER BILLING ME DUE TO YOU OWN CASH-FLOW issues. THIS IS WRONG and *******. Secondly you have had a contractor cutoff my electricity *******LY. As I complaint about them not doing their jobs. THEN you would not fix it and I had to pay to get an electrician reconnect me. I am going to publish this on Social Media, Internet and will put it in international news if you don't fix this. Apart from that I am going to also take it to small claims court for my time you waste, electrician I have to pay, and equipment you stuff up by having phase rotation wrong, and switching power on and off several times a day (this has ceased lately). Was also reason for me being cut-off after complaint about this.
