You obviously don’t like the bitchy answers you received so I’ll try to help. You have two avenues of redress:
1.Go to your Town Hall, tell them you hold the council entirely responsible for your misfortune based on the fact that they failed to grit the road on which you skidded. They will write you a cheque there and then for the full value of a new Chevrolet Kalos, five years free servicing and comprehensive insurance for your first year.
2. Contact your insurers, tell them you hold them entirely responsible for your misfortune for not telling you that Third Party insurance only covers you for damage to, err, Third Parties. They will immediately send you a cheque for the full value of a brand new Range Rover and pay for all your petrol for a year. They should also provide a hire car until your new car is delivered.
Is that any more helpful?
