Universal Vacation, Resort.com , Villa Del Palmar Flamingo's Puerto Vallarta do not honor the right of cancellation with the contract of vacation ownershp San Diego, California

I had recently visited the resort Villa Del Palmar Flamingos. Under the high pressure sales presentation with misleading information from the sales representative, I signed the purchase contract. Since I am visiting during a cruise, I was not able to find out the details until I got back home.  After I read the details on the contract, I discovered that some of the promise made by the sales representative are not listed. They mentioned about the unlimited usage in the summer week as long I pay for the maintenance. Besides, I found out a lot of complaints about their practice. I become worried and then decide to cancel it.After calling UVC, the representative only asked me to follow the contract instruction about cancellation. They  didn't provide any further help or instruction. I found the cancellation clause in the contract "Member has the right to cancel the membership within 5 business days following the next business days after its execution"  I signed on Dec 30,2010.  The next business day after execution is Dec 31.  It means that I can cancel within 5 business days after Dec 31 which is Jan 7. BTW, Dec 31 is a federal holiday too in US.  After tons of phone call to UVC, Villa group over 1 month, I finally got hold of the responsible person Joshua. Unfortunately, he declined my cancellation because he  said that I sent in the request 1 day late.  During my phone call  with him, he does not address the issue professional at all. He was very rush and said that I could post anywhere. He believed he is right. I asked him whether he has read through the case that he promised me a week ago to process. He didn't . He was too busy and he had a baby last week. I understand that he 's busy with his life but someone else should help.  I don't feel that he was listening at all.
