516-926-5093

this number is from Nassau ZONE 1, NEW YORK,  calls at 2 hour intervals.  I know no one in NY so I am guessing it is a robot call.  

Yep, robot call. Left 2 second clicking noises voicemail.

it bill collector Rash Curtis & Association

It is in fact Rash Curtis & Assoc. A third party debt collector who uses ROBO Calling to bombard you with calls all day and into the night. Call the number back after hours and see for yourself who answers the phone. They are located in Vacaville, CA. but the numbers they call from are from all over the US.  If you block one of their numbers to stop the calls theywill call you again from another  number. they have hundreds to choose from.

Report them to Atty. General and BBB. Do not stop reporting them until you get some resolution. They are bottom feeders.

Phone calls and nobody answers

I don't know this number.
