Sounds like you have a signal issue. BBC stations are carried on a different frequency to the commercial channels. Failure of some services but not others would indicate an issue caused by the wiring at your property, or a signal adjustment being required in the cabinet. Virgin will not be aware you have a fault unless you contact them.
