Really don't know what to do. Fence is between myself and neighbour. I have a driveway and front garden. Neighbour has parking that goes on to an unmade road. This means they can either park one car parallel with the edge of the road or two cars fronting on to the road.
A few weeks ago I got home to find fence panel broken - hit from neighbour's side with enough force to separate the fence from the frame. The fence was hanging onto my drive with the horizontal pieces pushed through onto my side. No idea how it was done but think someone from my neighbour's side either drove straight at it or reversed into it. I assumed it was someone using neighbour's space to turn round in the road.
I buy new fence panel and trellis (£70) plus fence post mix (£5) and arrange for someone to come and repair it (£20). Fence repaired and post re-cemented. Fence post had two supports left on it whilst cement set. One support on neighbour's side (as post was leaning towards their side).
Neighbour removed support before cement set saying he didn't know why it was there but he assumed a passer by had put it there - wtf?
It was obvious but I gave him the benefit of the doubt and said I would let him know when it was being re-done.
It was repaired again today. Had to get new fence post as it had been pushed and damaged. Also had to dig out old cement. 'Quite a job' according to the chap who did it. All in all it cost £50 for new solid post and labour. Again two supports left whilst cement set. Also note left in letterbox advising neighbour that work had been redone and also suggesting neighbour park outside my house as one of the supporting struts was blocking one of their parking spaces.
Checked mid-evening to discover both supporting posts removed (even the one that was onto the road and not affecting parking).
Went round to neighbour to ask why it couldn't have been left overnight. Got a lot of abuse (swearing in front of my 6 yr old who had come out the house to see the fence). Eventually neighbour said he hadn't seen the note (even though he would have seen the supporting post and would have known why it was there from our conversation last week). Accused me of bullying him. 
He was also very keen to say that the fence had been hit from my side and accused another neighbour of doing it (he said he didn't see it happen). I told him that I'm not interested in who did it, just in getting it repaired.
The post had not set when the supports were removed so there is a bit of a wobble that will need fixing (again).
I think by the neighbour's overreaction that he or his wife probably did the damage. The chap who has repaired it twice now thinks the fence post was deliberately pushed after the initial damage to weaken it (and damage the new fence - the post wasn't recemented when the new fence was fitted as it wasn't that wobbly). I frankly don't care if he did it or not but I don't want to keep paying for the same repair work. So far I have spent £145 which I don't have (half of my bike fund that I will have to replenish).
What would you do?
