I bought an item for my new baby via Facebook marketplace...we are struggling financially atm so I was happy to find this item second hand at reasonable price. Paid cash on collection. At home I proceeded to wash the washable bits of the said item, only then I realised that some crucial parts were missing. I messaged the seller and politely asked if he had these and could I collect them, he said he will look for them an let me know... and then I've heard nothing back, despite several messages he is totally blanking me...It's not much money (£50) but it's a large sum for me at the moment, and I feel so disappointed as the item is unusable without these bits...I know where he lives, obviously...would I be unreasonable to go back and ask for refund face to face? He probably won't even open the door if I do.. WWYD? I don't think there is any buyer protection as it was cash on collection...I'm kicking myself for being so trusting and not checking the item properly...I would like to get back to him somehow as he has knowingly conned me!
