A strange call

My mobile range this afternoon and I answered it.
"Is that Jenny *********?" "Yes."
"Do you provide counselling in the north Wales area?" asked the Yorkshire accented, male voice.
I sighed. Not a potential client, then.
"Are you ringing me to sell me advertising space?" I said.
"No." (Did I detect a hint of  innocent outrage?) "Why would you think that?"
(Could it actually be a potential client after all?
"Well," I said, "I have been getting a lot of that type of call lately and the way you began the call made me think that this was another one. If it isn't, then I do apologise."
"I'm not sure what's going on here," came the muttered response.
"Are you ringing to ask about counselling, then?" I asked.
Silence, then "Oh, I think I'd better ring you back later." Needless to say, he didn't.
So, there I was, beating myself up good style, bemoaning the possibility that I had let the counselling profession down and this man would be going away totally disillusioned, but Keith was on the computer, googling the number. Sure enough, up it came, the exact number, with accompanying warnings that this was a number not to be answered or to be blocked as it was someone targeting small businesses and pretending to be from an organisation such as BT with the aim of persuading them to part with their money like this
Phew! No need to hang my head in shame, then.
