There seems to be a lot of Chinese sellers on ebay now who are claiming to be based in Jersey, they seemed to have swam the channel from Portsmouth. Also, it seems that the have also been basing themselves in my hometown of Swansea. I contacted one recently asking to collect a lens adapter which they refused, when you look at their feedback, they are China based.
If I'm buying of ebay I prefer to buy from sellers with very little or no negative feedback, it just makes me feel safer with my purchase. Also, I only buy from sellers who specialise in the product field to which I am buying.
The shop where the OP bought from has history of poor feedback.
