My sister seems to have a specific problem and it seems to be worse. We don't know anything about the burnt out cars (why it happened etc).
Unfortunately when one has to drive 25 miles to work and get there at 6:30 am not being able to sleep at night for the noise going on next door is not an option. The other thing is that there definitely was a row going on and she has two very young kids. Again my sisters mistake for CARING !!!
These people seem to know what they are doing, and if they can't be identified on CCTV they will know it well,
If my sister goes the standard route of putting the house up for sale she still has to wait till it is sold hoping that they will not damage it while it is up for sale making it clear to a buyer that there is trouble and changing their mind about buying it, this is not just about furniture but a whole new branch of trouble including the upheaval, just moving is not that simple. She is being watched, the very day the fence went up they damaged the car, I had infact I advised her not to replace it with anything but she is stubborn. Personally I would have left the wall sprawled all over the pavement and not even moved it.
We have a friend that used to live a few doors down, they moved out because of problems but they could afford it, infact they now rent the house out. Unfortunately she did not know my sister was moving there.
