Thanks for your reply. Are you sure they cannot send any one around for the collection of these funds? Also, would it be wise to atleast email / mail them evidence of everything to attempt to close the case? Its the exact same letter as others have posted, word for word but with my details and amount.

I'm completely confused and worried as these solicitors have sent me a letter for an Adidas order which was £900 and it was mostly returned, 5/7 items were returned due to sizing issues. They have stated I have 14 days to pay and that my items were not actually returned to the retails. This does not make any sense, I had done various orders and returns with them before and never had this. I have confirmed with adidas themselves that the items had reached their warehouse and have confirmation emails stating this too. The figure of 1600 is out of the blue, they must have taken my previous returns into account or something? What really worries me is that people have stated in other areas of the web that they have sent bailiffs or threatened this multiple times, I'm young and live with my parents so that wouldn't be good for something I didn't do any wrong with. My idea is to gather everything I have as evidence and send this directly to dwf, Is this the right thing to do?
