mate ebuyer will sort you fine just keep on your toes, i ordered a 3500 winchester at beginning of year and received a newcastle
i mailed them by enote or whatever and they sent a courier to pick teh chip up free of charge, they then emailed me to tell me my payment has been refunded, but the cheeky gets didnt refund the shipping, so i mailed them and said where is my shipping charge that i am entitled too, which they promptly refunded no questions
so like said, keep on your toes and you will be fine, overall turn around time for me 2 weeks (not great but 4x faster than dabs on my xtpe rma, yes 8 weeks from rma request to refund) )
