INCORRECT BILLING

Last month I complained on this platform about being billed incorrect high billing without my fault, and I did not get any response or a caretasy call from them, tha way they dont take their customers serious, and hey went on and billed me more than double my monthly pay R224.90. This month I received a statement that I(9 will be debited more than triple R663.90, what on earth for? I dont owe Telkom this much, can someone address this issue urgently. I AM NOT HAPPY WITH YOUR CUSTOMER SERVICE AND YOUR FINANCE DEPARTMENT.
