Someone uses my email address

A while ago I started receiving emails from Verizon, the first one being a notification that "my" email has been changed successfully which means someone must've done that mistakenly. I am not a Verizon customer and never have been, I created this community account just to post this since I didn't know what else to do anymore. This situation is both problematic for the person that owns the account and annoying for me. 

Can anyone help me resolve this?
