Thosand trails Barbara I signed contact but i was not given a copy changed my mind Whitney, Texas

I was never given a copy of contact and changed my mind in 3 days left the park after six weeks. they tell me even after writing a letter i stayed a week and no money was due to me. how was i to know what to do since i never saw the contract. the man who sold it was new and is no longer there. ive been given the run around thinking i had canceled in the right way but if they would have told me a week was 400 dollars wich i didnt think it was aweek this is wrong. i was given false Infromation from the starting
