Virgin cabled my street up about 2 years ago and I was always with Talktalk on FTTC 40/10 and 80/20, on one of their 'fixed' price plans
Saw my arse when they said they were raising prices earlier this year so signed up via a Virgin rep - deal was good and promised no set up fees and a £50 amazon voucher and £50 bill credit over the phone
First bill came with £35 set up fees, rep vanished never to answer calls or texts
Had to battle with Virgin customer services to get the set up fees waived and raised a complaint about the rep as I had never received this voucher (they said it would be emailed within two weeks of going live)
Again, battled with customer service after my complaint was 'I cannot get hold of your sales rep' to which they replied 'We won't be able to either so there is nothing we can do' - madness! In the end they did credit me with another £50 after multiple calls
The service itself is generally very good - I did buy my own router as the Hub 3 supplied has poor range and my partners iPhone constantly had issues connecting. Running the hub in modem mode and using our own router is much better. I am on the M100 package and wireless speeds are consistently above 100mbps
Cityfibre are cabling our area up in the next year or so and I think we will move to another provider when the Virgin contract is up, unless Virgin have some very strong offers.
