adsl line

I just moved into a new house in allie lucas str in eldorado park in jhb south. I app**** for a normal Telkom line order nr *** to convert to adsl via mweb and they said they won't replace the cables ****** in my area and that I must look into wireless solutions. I tried about 20 different isp's and other companies like neotel, iburst, bitco.....etc etc. but no one seems to have coverage in my area including the very same telkom. How do I go about this
