Complaint Against a Service United States

Yahoo! / Somebody else is using my email address.

I know that somebody else is using my email address because I received on a daily basis an email that is not for me. It is the same name. How do I go about blocking him? I do not know this person personally or have not made any contact with him at any point in my life. I know that it would just be easier to make a new email address but my current one is connected to every transactions and accounts that I have and it would be so hard to trace all of them and change it.

my email address is [protected]
