Let's hope they train these people better than their current crop. Had G.Fast installed, had to tell the engineer he needed to give me a G.Fast modem and he neglected to use the UTP RJ11 cable from my master socket to the modem. That latter mistake knocked 20mbps off my speed until I found the wire in the packaging he'd left. He'd also swapped the pair my line was running on as he'd supposedly found a fault. It was meant to run the same route but I'm getting considerably less than my estimate (160mbps rather than 252). So not impressed with my experience, still can't get more than VM's top speed either which grates.
