Who called from 8607560772

Called looking for (it just happened to be) my mother-in-law.  
They had her name and address but wrong number.  When I inquired what it was for, they informed me it was the "recovery department" trying to recover money withdrawn from her account.  I asked them for their number and I would have her call them and they hung up.

Just received a call from the same number, but they hung up as soon as I said hello.

This person just called me and stated they were from general electric providing a service.

I hung up on them and told them not to call again.

I got the same call, only I looked up ge security systems online, and there is not one in West Haven, CT, which is where mine said he was located.

Received a call from this number about 15 minutes ago  (roughly 4:15 PM)- I live in central CT and this would be a local call.  The caller hung up on my answering machine, the number came thru "blocked unknown"-  When I called the number back (didn't have to dial 860 prefix from Hartford area) I got a recorded message "The number you have dialed is not in service at this time".. Pretty strange.
