i have received to lots of information, one is a loyalty card for a shop and the other is confirmation of a ticket sale for a person with a similar name to me, but is using my email address. My bank account has not been frauded as I have checked. How do I complain to yahoo and let them know what has happened and how to stop this person using my details?

You can tell if someone else has been using your account by reviewing your Recent Sign In Activity page. Look for unfamiliar IP addresses and log in locations. These will indicate that someone else has been accessing your account.
