wrong product

I app**** for landline from telkom but was amazed when I return home that they instead inserted Adsl. I immediatley phoned to complain but no one came. I phoned again numerous times to advise that the pr oduct they supp**** is not the one I asked for. I was always promised thT somebody will be send to my place but that did not happen.. I was then referred to a manager by the name of Floyed when I refuse to pay the monthly billing and he advised that my matter will be referred to a lady who is going to relieve him as he is going on leave. When realising that nobody is contacting me I then send an email and immediately phone. I was then advised that the charges will be reversed and the line will be converted to the land line which never happned. After some months the people from attorneys started phoning me advising that I was listed by telkom I need to pay immediately. I still do not get any response from telkom as I requested proof of the contract to apply for adsl or statement of the landline if it was used as I do not know what am I paying for. Telkom should be the one apologisingto me as they placed a wrong product in my house,, fail to correct the situation and harras
