Calls, no message. Blocked

Calls, leaves no message so,I  blocked it.

30 calls from numbers just like this, they call and some leave messages about my loan (I don't have a loan) duh, some just call and hang up.  I block it and in about a month it starts all over again, so irritating but I don't know how to make them stop.  Do NOT believe any number you don't recognize!

This number called me saying that I had filled out an application for an auto loan.  When I said that I did not apply for an auto loan, they hung up.

I received Multiple Numbers from a LOAN PLACE that I've never even signed up for a loan. BLOCKED, but like there good call center s they do have a way of changing to ALL SORTS OF CONTACT #'S, so I'm screwed I guess.
