Driver Support False claims of service, remote invasion of PC, provided no registration code despite payment, no service Internet

Contacted website, downloaded software for scanning my PC for driver updates. Paid for registration by credit card. Had initial problems and was advised to phone a technician who then offered remote service. I allowed the remote service and the phone-call dropped out. I was immediately rung by another technician (a male pretending to be the female person I had been speaking with previously - obviously running to a script - and he began a sales pitch I have heard a thousand times from Indian or Pakistani telemarketing companies about how slow my PC was (having only just reformatted and rejuevenated the PC). Despite having paid my $48 for registration I did not receive an activation code via email as promised, and cannot use the software I have downloaded.
