I've raised £1600 to move house due to ongoing targeting by bullies on our house and son

We are in need of help getting a house move due to ongoing terrorising from bullies on our house and kids . our house gets targeted all the time from bullies trying to smash the windows and egging it we have gone as far as moving our son school and stuff to stop this from happening we have had the cops the school and social services and even the local MSP to help with this matter and yet nothing has being done.
My son has being threatened to get stabbed and also pushed under a bus and he has also being jumped by 5 boys now this sadly mounts up on a 15 year old that seeks no trouble
The in pact this has had on all of us is to the point that we all in need of counselling while 3 of us now are getting and sadly because I am medically unfit to work we rely on social funds to get by on a weekly basis and to get money to move is out of reach for us because with private rent they seek a deposit and a month upfront and the costs of moving
We appreciate any help that can be given with this and thank each and every one that is willing to help
