What exactly is the problem - I have many clients and friends who use Telefonica BB quite happily (as well as other suppliers). Tell us a bit more about what speed you pay for, what speed you get, and how much you pay - and I see if I can make any sensible suggestions.
I live in Almeria, with no telephone line! So I have a microwave system. My costs for BB are high compared with the UK and Spanish ADSL, and speeds not great. I wish I could get a telephone line (but I can't).
I presume you do realise that in order to have ADSL you MUST have a telephone line - that's what the ADSL connection uses - there are no cable systems that I have come across here.
However there are lots of *deals* for BB and telephone combined, which are really very good.
So let me know more about your situation, and I'll see if I can point you in the right direction.
