It's some company that says that a fictitious survey came up saying that we were moving our offices.

Fictitious because we never participated in any survey and our office has been here 107 years with no intention of moving.

Ignore it...some type of scam

We have been getting calls 2-3 times per day.  When I answer, there is no one there but it doesn't hang up.

Have received 2 calls today.  When I answer, there is no one on the other end but it doesnt hang up.
