Neighbour is trying to say one of the fireworks I set off landed on their cars roof. Came to my door and admitted there was no damage and to be “careful” with the direction they’re pointing(towards the sky) have proof of this. Today they’ve came back and said that there is damage to the car and I’ll be expected to pay for it to be fixed. They have no proof it was one of mine but apparently have another neighbour as a witness. No Dashcam or cctv to say it actually did land on the car. Is it worth taking further or not worth entertaining them?
