Hi, i recently ordered a bed online and signed for delivery after the courier refused to take the item to our third floor flat. upon taking the items to our flat we noticed a strong smell similar to white spirit. on opening we realised the bed head was covered in white spirit (a serious issue as its leather upholstory) and part of the leather was torn. we tried returning the item but the sellers are claiming by signing with courier and in accordance with their terms and conditions online i actually signed to agreeing the item is in good condition and that it is impossible that the supplier or the courier would have handled any white spirits or similar near the item. do they have a case or is there something for me to fight for?
