I got 3 calls from similar area codes and a caller id that said Fitchburg, MA within 3 days. Each number was different. The other two numbers were 978 502 3864 and 978 502 9805. So I got sick of it and called the 8274 number from a pay phone. Yes, they exist. A woman answered and kept saying Halloo Halloo. Then I canned the 3864 number and the voice mail said I had reached a Jack Francis. So perhaps someone is stealing caller id's.
