I was working on my computer a couple of days ago and I heard the phone ring. I let the answer machine pick up and I heard a voice. But when I got to the phone, it was obviously a recorded message. Full text was something like, ",,,press 2. If you are the named person, press 1 otherwise press 2. Sorry there appears to be a problem."
I have caller ID on my phone, which just showed "International". However, there is a separate caller ID device that BT were giving away before I got my current phone and that showed a number.
The number called back later but when I picked up the phone I got a dead line.
Then I got several more "press 2" messages on my answer machine over the next couple of days.
http://whocallsme.com/ didn't have the number listed. Another came through this morning while I was hoovering and I hadn't heard the phone ring. So I phoned the number.
It was Habitat. I had ordered something from them through Homebase in Guildford on Monday and they were trying to arrange a delivery date. They have now given me a date. They are supposed to phone me back nearer the date. I hope they use a human to do it.
