I just received a call on my VirginMedia line from 01747228096 and got an automated message telling me the caller had a special offer that was only for BT Customers. Are they just being a tease? Is the special offer a deal on a Virgin Media account?
I was then given the option to 'opt out' of further calls. If you are ever given this option don't take it, it's the fastest way to get yourself / your number onto a 'suckers list' that makes you more valuable to other unwanted callers.
