Due to the Corona Virus there are currently 3 ways to end your contract instead of the usual 2 methods.
1) You could try the text messaging service. Just send a text with a description of cancellation to 07533 051809. Your message will go into a queue and a representative will respond to you as soon as possible. It may take a few days.
2) You can also call 150 from your Virgin landline, or 0345 454 1111, but best to call at 8am to avoid call queues -
The lines are still open, but some people have heard the message that the lines are closed. A member of the Forum Staff has fed this back up the chain. Usually from what I've seen when customers redial the lines are open.
3) Or write to them to as per the terms and conditions. If writing send it by registered post.
