Got a call today from 678-337-7664, caller left a message looking for my NEIGHBOR! She's elderly and well enough off that I'm sure she doesn't owe any money. Caller ID says "Green Tree", which, according to their website, is "one of the country's leading servicers of home loans". He left phone number 800-852-7751, said his name was Kevin. What I want to know is how can these people get away with pestering people's neighbors?
