Telkom charging Forfeiture fees for non Contract

Telkom advertised a package of R425 for 10MB Uncapped ADSL and R 167 for line rental, incl.a free DSTV Decoda. A contract would be required if I wanted a router - I did not need one. I ordered via the call centre.The order was confirmed on 16 Jan. After first billing it was found that this was not an uncapped facility and this was more than what I could afford. Went to Telkom shop in Tygervalley - spoke to manager who changed the package to uncapped ADSL - within the price parameters that I originally wanted. No Decoder was ever delivered - despite this being offered as a free gift. When querying this - they said I had to enter into a contract (despite the advert saying it was free) and in principle, I refused to enter into a contract. First they bill me for the Decoder which I dispute. on 18 March they credit my account for the decoder. At next billing - they charge me the same price as the decoder - as Contract forfeiture fees. I dispute this with the call centre and they submit a dispute - today I received 2 sms's that threaten me that my line will be suspended. I submitted another disputed again today - it seems fruitless. Without my Telkom line - my business is closed.
