I recently moved house and as others have found Virgin have changed me over to a new contract with an 18 month minimum term and a price increase midway through.
This clearly contravene the terms and conditions on the website:
"Where we have agreed with you to continue providing the same services that you received at your current address to your new address and this is during any minimum period, then that minimum period will continue at your new address (for example, where your services are on a 12 month minimum period, if you move during month 7 of your minimum period, the remaining 5 months of your minimum period will apply for those same services being provided at your new address)."
I spent over 2 hours trying to get this sorted on live chat. First customer service dropped my live chat and then complaints are refusing to acknowledge the problem.
