I sold a pram on Facebook marketplace. They came, saw it, took it away.
A few days later they complained about the condition of one of the tyres. As an act of good faith I said I'd send a replacement tyre to them. They said no, they would like a refund. After saying that isn't an option they came back to my house to argue about it.
The main part where I need help is that they left the pram here, said it was mine.
I'm not sure where this puts me legally in having it here. My instinct would be to message saying words to the effect of "you left your pram here, I will keep it safe in the garage and you can pick it up at your convenience" perhaps with a time limit after which I'd take it to a charity shop. I'm not interested in selling it again.
Is this sensible?
