Horrible Services

I had an ADSL line with Telkom, I moved from my previous place to my current one, asking them to move my line, in the process of moving, they installed 2 lines in which one of them I did not ask for and I was not using, therefor I was billed for 2 lines, when I realized this I stopped paying my bill, told them that I will not be paying until they sort this out and send me the corrected bill, nothing was done about this, they suspended my services as I was not paying them, but my bill kept increasing, I went to their Cresta store to try solve the problem, nothing was done about, my bill got to 4k and still growing, now they have lawyers on me, I recently got a message from their lawyers saying they handing me over to the credit bureau, I'm very upset now cause they too quick to want money but their services are nonsense, as far as I know customer's needs have to be met first before payments.
