Had exactly the same experience but for some grado sr60 headphones- asked to send a postal order to  M Joy EBC House Riverside View Thornes Lane Wakefield WF1 5QW. 5 Days later no headphones and contacted sidozey via ebay email to be told he had been on holiday and had his ebay account hijacked and that this had been reported to ebay. My item had also been removed, and you cant report it  as not received until 10 days have passed- i've emailed ebay direct and reorted it to the police as fraud and theft so wakefield police will hopefully pay that address a visit but after googling it it looks like a commercial premises with p.o. box facilities- good luck to anyone else who has been caught out!
