Just got my December bill and found I'd been billed £28 for a premium number I never called. No-one in the house could have made it either. Lots of reports of it being a scam number on
http://whocallsme.com/Phone-Number.aspx/09083916319 too.
Virgin agreed to drop it, but I slightly resented it being implied that because the Phone Pay Plus website said it was an adult service I might therefore be more likely to be at fault. Don't customer services have an internal database that keeps track of numbers where there's been a problem?
Charging £2 a month to bar premium rate calls in these circumstances is pretty poor...
