Adsl line

On the 13th August i had called Telkom requesting my line to be changed to a ADSL line . I was told to pay R700 for the line to be converted.I then called to find out if it was converted I was to it will take 14 days. To date the line has not been converted. I called again to find out whats happening, Telkom now says that there is no Infrastructure in my area for ADSL. I have told the them that i do not live in a Rural area and i dont understand as there are other people in my area that have these facilities why cant I also have them.I was then told that i dont live close enough , so I ask the consultant must i sell my house and move closer for Telkom convenience. I fail to understand why would they make me pay R700 in the first place they knew the line could not be converted.
