Their web site says: "If you are not completely satisfied with your membership, you have the right to cancel within the first 30 days from the date you receive your membership material and receive a refund of your membership and processing fee." However, read the fine print to make sure there aren't any gotchas in there.
In my opinion, this is another MLM (aka pyramid) scheme and they make most of their money from folks who sign up, pay the $299, and give up after a few months of wasted effort. You might try googling "fortune hi tech scam" and "fortune hi tech ripoff" and "fortune hi tech pyramid"to see what some former Fortune members say about it.
