Virgin certainly do a lot of cold calling for some of their other enterprises. I remarked to one foreign sounding gentleman that Richard should concentrate his efforts on getting his trains to run on time. As this resulted in a pregnant pause, I expanded to Richard Branson, but the caller was still none the wiser as to what I was talking about. I declined the offer of energy supply or credit card or whatever.
the problem when people call your home via phone or in person you never know if they are real ( ie the company they say they work for) so i never deal with them there and then, i will always call the company direct.
Jester, make sure that the credit card company dont allow any payments...well you never know.
Try phoning 0845 6501000 and ask if they know about this call or if a account has been set up in your relatives name. They might ask you for your relative to call. You might have to wait a while phoning late in the day but they should put your mind at rest. As said above it might be too late. I hope not.
