I am in exactly the same position, installation took place 23rd July and I was initially told the TV would arrive on the date of install. I've contacted Virgin 6 times since then and have been lied to repeatedly, given false delivery dates, initially told 14 days after installation, then by 3rd September, then by the 19th, then told it'd be a minimum of 58 days after installation, I've raised 3 separate complaints, was told last week someone from dispatch would contact me within 72 hours, heard nothing, told the same thing again this week, still no contact, have called again this morning and another form has been raised for non-delivery of gift. We're now at 65 days since installation and still, nothing. In the meantime we're paying for an additional service box which was for use with this TV.
It's absolutely appalling service from Virgin Media, had we known this was going to be the case we'd have gone with Sky and got the SkyGlass offer, or better still taken out a cheaper contract with another provider and bought a TV. I will be reporting to Trading Standards and the Comms Ombudsman. Customer Service is absolutely abysmal, it takes 15-20 minutes to circumvent the automated service to get through to an actual human and once you do get through the agents have no idea. Advice to anyone thinking of going with Virgin - DON'T!
