Stuck in a rut

I first app**** for a contract about 2 yrs ago while staying in a complex. Telkom installation was speedy and I was greatly impressed by their professionalism. However, only a year later after moving to another address the issues started. While Telkom were busy moving my line, one of their technicians informed me that he could not provide the 4mb speeds as per my contract, as there was too much \noise"on the line. So now I am paying for a 4mb line speed"
