So, at work, I get a call from what looks to be an overseas call, from a "Mike" making enquiries as to whether we were planning on moving etc, I've had a similar one claiming to be from the Chamber of Commerce a couple of years back. I was guarded and they hung up.

I am not sure what they were trying to determine, it's part of a scam I presume, but has anyone else experienced this or know what they are trying to achieve?
