(603) 552-9888Dangerous

Yeah they’re back. Got a call this morning about some documents that needed to be signed by someone with my family’s last name. What tipped me off is the first name they used. No one in my family uses that name and they hung up after I told them that there wasn’t anyone here with that name. Though gotta give props they were at least polite and apologized for the call before hanging up.
