Who called from 2053235400

They called me all the time and once the man started yelling and got abusive. He claimed to be a lawyer.

This is a collection agency. They are trying to reach a person who must have had my number before (I got it 6 months ago). Asked them to stop calling but that didn't help.

I keep getting calls from this number and I am not who the message is for.  This is getting very annoying and bothering me.

Collection Agency.

Person continues to call me asking for someone I don't know.  He seems to think that because I have the same last name as the person he is looking for then I should be able to help him.  Is there any way to stop this type of phone call?
