Confused by the words you use..Exchanged it!! Normally means, swapped it for another Destination/Resort.
If you Sold it!! Who was the Buyer?? 1n terms of what you can DO!! you still own that week! So you can
still Sell it!! Place it on e-Bay, or such sites, Gumtree, etc..with a starting Price of £0.01.p. and take it from
there!! GOOD LUCK!!
