You don't have to contact the seller, just open a Not as Described case under the ebay money back guarantee

Seller must send a prepaid return label for you, and if they don't you escalate the case.
Have a look where the item location is, if it is the UK you only need to return it to the UK. Chinese sellers have a habit of asking yu to return items to China, but you don't have to unless the item location is China.
