Bourne Leisure review: Let to offset

Please explain to me why it is that your Haven caravan park seem to think that staff seem to think that when it comes to selling a caravan miss-representation, breach of contract, and incompetence that leaves their caravan owners suffering with physical, mental and financial stress is no more than a minor inconvenience.
After saying I could not afford the finance on the caravan IO was told join our let to off set scheme And we will pay you enough money each month to pay the payments, great, until I try and get the money I am then told oops no sorry that's wrong you cant have the money till the end of the year. I do not have the income at 78yrs, to pay the finance and nothing is being done to compensate me for your staffs mistakes
I was also sold a caravan deck which states the deck is 16ft x 8ft with side steps and gate, the deck I got is 12ft x 8ft with no steps or gate.
