Vox Telecom playing the blame game when it comes to PATHETIC service!!

The worst experience of my life is with these people. I am using Vox Telecom as my supposed service provider on an SADV FTTH line installed for little more than a week now by Vox. And during that time if the line was up for more than 5 days continuously, it's a lot. SADV keeps on blaming VOX, my service provider and, VOX, on the other hand, keeps on blaming SADV and I am sitting, in the middle, paying for a PATHETIC service - or rather, lack of said service. So much for FTTH, as it seems to be worse than an ADSL line. Vox why should I put up with this, give me one good reason? Let's see if you have the guts to reply and come with a resolution. Because the next time this line is down you can send you contractor within the hour to remove your equipment or I promise, I WILL SURELY REMOVE IT MYSELF AND YOU CAN COME AND COLLECT IT FROM THE PAVEMENT! Your FTTH is 100 times worse than the ADSL line I have been using for years now.
