An Electrical Theory Question I would like to ask someone with this type of knowledge?

I recently had major faults with my wiring in my mobile home, my electrical supply was sut of from the mains and becuase there had been major faults in other areas of the park home site where I live, I was told that due to my poor wiring in my home, in turn that caused the nutral to go from 0 to a reading of 150. Can someone please tell me, with the reading of 150 on a nutral cble coming into the property, would this mean that there was a fault on the main suppliers nutral coming into my property. This is causeing me great stress because I am being blamed for about 7 contents damages in other units like computers and electrical boiler meters and one mobile home was burnt down, but with this the fire report said that it was an electrical fault with the computer wireing because the socket and main electrics were still on when they fire brigade arrived, but the park where I live are blaming me for this fire and i am so scared. I am being taken to court by the park who are seeking to have my contract terminated. I am so confused because when I try to find ou what could have happened, some people are telling me it is deffinatly the fault of the suppliers nutral that showed up ,my poor wireing and hence caused these damages to others on the park. I am trying to find an electrical company who would (if it is true that the fault is on the supplies side) that I can have something writen to hand to the court to confirm that they are to blame. I had my problems that started with Rats eating through my wireing and I had someone in to sort it out, but then the rest of the park went down. Please can someone advise me.
