Offered a hosepipe for sale on Facebook. Item is used but not by me/ at my house (I got it on a pallet delivery of lots of items). Item is photographed from many angles. Advertised as "wall mounted 20m hosepipe" no other info apart from price and multiple images. Image shows make and model as well as condition of box and item.
Item sold to someone on Facebook market place - price agreed is 25% off advertised. Person comes to collect it, tries to haggle on price due to used condition. Told X is price,take it or leave. Continues to try and haggle, eventually pays agreed price.
Contacts me today to say it doesn't work and they'll be returning it. Told I don't take returns. Has now turned up at my house, again told I don't take returns and asked to leave. Continues to argue with me so I close the door. Is now threatening to call the police.
What would you do? Item was £15.
