Hi,

Please help ASAP and freeze my account until sorted as someone has logged into my eBay account and changed my password and set a new email account (it showed as c*****@yahoo.com or something like that).  I have never had a yahoo acount and like my user ID slickchick_21, my email address was slickchick_21@hotmail.com

Following reading your instructions I have changed the password on my personal email account but I am unable to log in to my eBay account to switch things back.  I was able to temporarily log-in via a password sent to my mobile (they have not changed my mobile number) and so far cannot see that they have tried to use my account to buy anything.  I have also been able to update my security questions but cannot change my password and now I am getting a message saying that "Unfortunately, we can only send the code a certain number of times. Please sign in with your password instead."

Please can you assist with getting my account secure ASAP?

Many thanks,
Laura
