We are with Virgin, it's the standard for the building we are in, so no installation fees. Good service except for a couple of hours each night when things can slow down. Generally have two laptops on VPN, tow iPhones, two iPads and the TV playing things from netflix with no real issue for most of the day.
Having said that, we just had a break on service yesterday morning. We reported it at 3.30am (don't ask!). Their support phone jockey insisted it was the modem, I insisted it was downstream somewhere in their network (pretty bloody obvious given the modem status)...they insisted again and we were told an engineer would come - on Tuesday next week. They then called back at 8.30 to tell me it would be fixed by 1pm yesterday as it was a downstream issue that affected multiple people (approx 2,000)...told them I was disappointed they didn't care enough to send someone for just me by that time; and that they hadn't believed me in the first place.
A customer service guy should be contacting me soon...hope it's something substantial as a way of apology.
