Who called from 6158438448

It's a company called Credit Management.

Annoying.  Calls all the time.  Nobody there when I answer.  I have no debt, so no clue why a debt collector would be calling.

Someone from this number continues to call our residence.  They have the wrong person.  How can we get them to stop?  

This number has called me every day for the past week - when I pick up I get a dial tone or dead air. Caller ID labels it as Optimum Solutions. Getting annoying...

I have had several calls from this number over the last two weeks. I have no idea who and why I am being called. It comes across the caller id as Optimum Solutions.
