Pathetic service

Its almost a year after numerous disputes opened and many hello Peter reviews and my account still hasn't been sorted out. I took this as 1 of the things that won't go away as the bill kept increasing and I just need to pay and wait for my contract to end but to my surprise it doesn't seem like it will end. On 4th Aug I went to Telkom Mall of the south and advised the constant that I want to settle my outstanding debt, he printed the statement for me and i paid R 1884 08 as per the statement at Game store right away. I was advised my line will be opened in the next 7 days. Almost 10 days later I'm told I'm still owing R 901 for August as my line has been cancelled and closed. I was advised that I have to pay for the line to be reinstated. However should I not with for the line to be reinstated I will still pay the R901 plus the subscription fee. Why do i have to pay so much money for a closed line on a R150 contract. Is telkom a money making scheme that doesn't even care about their customers.
