Offered through Spirit Airlines web-site, Great Fun promissed 50$ refund of air fare after paying 1$ trial membership fee. Disregarding the cancellation for great fun trial subscription, never sent any coupons, this company kept charging my card 16.99, and after my bank started fraud investigation, promissed to issue a refund. If money is not receieved, I am starting a class action/fraud case against them.
