Grand Incentives Vacations of California Hard pressure sales San Francisco, CA Nationwide

I have terminal ovarian cancer and I was hard pressured into renewing a membership to a travel company, Grand Incentives, Inc.  They have called numerous times and I said NO.  I have never used the membership and was no longer interested in continuing it.  

Several months later I received another call from a pleasant gentleman who I told of my plight and he was very understanding.  I told him I no longer wanted to continue this service.  He informed me that it is transferable to my family and that I had a lot of money already invested with them that I would lose.  After much hard pressure I agreed to extend for 4 yrs for $369.  When I received my credit card bill the amount charged was $589.

I immediately called the credit card company and asked how to despute this bill.  They informed me that a form would need to be activated and they would issue me another card.  This was Friday June 7th.  On that day I also received the package from Grand Incentives.  After speaking with the Credit company I informed them I was cancelling the contract and wanted a refund.  They informed me NO refunds are granted after 3 days.  I have not signed any contracts with them and they charged me nearly double the amount agreed upon.

I no longer wish to participate in this program at all.  They do not have anything to offer me that I can't find on the internet myself for less money.

How do I proceed to get the money returned to me?  Do I need to contact an attorney?  I have reported them to the Better Business Bureau.  Is there anything else I can do?
