Thanks for your post on our Community Forums Ongman84, and welcome back!
Sorry to hear of the uncertainty over the phone number calling you.
This does appear to be a Virgin Media phone number that's called you, but we would warn that sadly phone numbers can be spoofed and could still work as a scam call under the guise of Virgin Media - or any other big company for that matter.
If you can give our team a call on 0345 454 1111 or 150 from a Virgin Media landline phone, our team will be happy to see what renewal offers are available to you.
Thanks,
David_Bn
