Received a call from this number on my Federal Government phone. Caller left no message, but I suspect that they are debt collectors since I've been plagued for more than a year by debt collectors looking for a particular individual. Debt Collection agencies sell, then re-sell their databases, so no matter how many times a person asks to be removed from inaccurate lists or from recycled/resold phone numbers, the next agency to receive the debt collection database will call anyway.
It is a collection agency, I got a call and they were looking for a person name "John-----". After advising them no John listed at the given number, they appoligized and indicated they will remove the number from thier list.
