Who called from 2123618062

They call me everyday a few times a day and they don't leave a message.
Even the name of the company don't make any sense.

Called and asked if had apartments for rent and/or landlord

This caller said they worked for the City of New York asking if I had an apartment for rent. I have no idea if they were actually from the city, or how they got my number. It seemed very questionable.
