Hi behouse,
If calling 150 from your Virgin landline, or 0345 454 1111, it's best to call at 8am to avoid call queues.
You could also try the text messaging service.
Just send a text with a description of TV Faults 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.
have you tried clicking on Check service status at the top of the page to run a fault test?
