Even Mr Google has never heard of ' Maphronite'.
Is your bank account showing a payment was made for this ' item' ?
If you are sure no one has access to your eBay account, might be worth changing your password, contact eBay Customer Servies and query if this was a purchase made, as you have no knowledge of this. Contact your bank too, to report an unknown purchase.
I would recommend changing passwords on all accounts you own, especially our email account and keeping a close eye on all accounts for the following weeks for any untoward transactions.
This is the easiest and quicket way to contact eBay Customer Services, for a Call Back option.

Lines open between 8 a.m. to 10 p.m. on weekdays.
9 a.m. to 6 p.m. on weekends.
I recommend contacting CS very first thing in the morning, when the lines first open, as there's more chance of Dublin answering.
