Recently noted that I had an email saying that I had an item for which I had not completed checking out. It was for something that I had not ordered, nor would I order. It looks like my ebay account was accessed without my permission, however they were unable to get my payment information so the purchase did not go ahead.
I have tried to report this to Ebay but they don't seem to have a method to report suspicious activity on an account, nor do they appear to have any interest in this.
As per their on-line advice, I have changed both Ebay and Paypal passwords. However just a note to be wary of your accounts and check the activity on them.
