Apple Trade in UK iPad

I recent purchased an revision 16 iPad direct from Apple UK. As part of that deal I did a trade in. Value of the Trade in was only £60 for a revision 3. Which was in perfect condition and working order. However I thought I would upgrade to a newer version before It would no longer upgrade iOS for security reasons. Now I've just been sent a new valuation via e-mail.

Apple Trade In Your Device:

iPad Air 3

Serial Number: removed

Estimated Trade-in Refund:

£60.00

Revised Trade-in Refund:

£0.00

The trade-in value changed because:

LCD display burn in damage/streaks/discoloration across the screen

As i know it was in good condition and have photos to prove it i clicked on the link to have the device returned to me. This did not work and sent me to this page.

So i guess this is a 3rd party looking on the community with no obvious way of contacting them. Does anyone have contact details for trade in items. I have the post code from the proof of posting LE174WJ.

Any help is apreciated.
