This was one of those popup adds that popped up while I was looking for cheap airfare. I don't remember which travel site I was looking at.
I quickly looked over the GreatFn ad and deleted. How they get your info is beyond me. I was charged 11.99 for the past two months. The phone # on my bank statement in "out of service".
When you get the # from their website, 866-428-3383, 877-488-9480, the service people are cocky and will put you on hold till you have to hang up.
BEWARE!!! GreatFN is no fun at all.
It is an absolute RIP-OFF scheme.
