Telefonica are notoriously slow to set things up, (3 weeks is normal) I had to bribe one of the guys and retain him with a few euros, and he would come out instantly
They do take a long time to setup and their networks are riddled with viruses, so you always have to have a firewall in place before connecting. One of the guys I knew just got his connection and a new machine, was in the house with the the telefonica guy plugging it all in, and as soon as he powered it up (without the firewall) to test it on telefonica ..bang viruses ...blaster the lot ..The telefonica guy said the network is riddled and apologised...
The locals call them Timofonica, which translates them to being in league with the devil.
Apparently BT are advertising that 60% of their customers are coming back to them, whereas the reality turns out to be that their customers are going to others in droves, 60% actually.
