Yesterday afternoon, around 16:30, I answered the phone to a female who just said that I should phone the following number to arrange delivery of a radio. She gave the number (07011 134542), said goodbye, and before I could get a word in, hung up. It didn't sound like a recorded message.
I have not rung back as no radio has been ordered and I therefore think this may be some kind of phone scam. Of course, it could just be they dialled the wrong number.
I have had a similar thing happen. I think that the scam is that although costs per minute aren't too horrendous (certainly compared to some 09xx numbers etc) the scammers have an answering machine which holds you on the line for a while, all the time costing you csh.
Only a few pence here & there over a month can add up...
