Just got this call, and they actually left a message;

"Uh yeah...if your company can take an additional local referral work, this is regarding an exclusive territory, please call 5715263662, again, 5715263662."

Unfortunately, their phone number does not exist, and they did not identify themselves - nor did they tell me what company they are calling from.

Hmmm, let's see; unidentifiable phone number which does not exist using a Google search, caller who has no name or identifies the company he is representing, wanting to give me referral work - most likely for money which he would ask for over the phone...

I don't think so scammer. Your number is now added to my spam list.
