Hi,
For me I had a similar problem and it was the white (rj45) 'phone' cable had come loose from the small box on the wall - while I was switching everything back on after a long trip back home.
It needs to go in and 'click' in place to make full contact at both ends.
I called the helpdesk but they could not help (as the cable was not connected to the box correctly).
The same engineer who installed everything first time called me next day and came out to fix it.
He advised to just call him (the engineer) directly to make the appointments next time - as he had to come out from Olhao to Salir (~45-50 minutes drive) for me and had been in Loule (~15 min drive) the day before, so could have passed by earlier.
[ I do have a Portuguese mobile phone - so don't know about the need for one ].
I hope this helps
Ian
