Complaint Review: GREAT FUN CENDANT CORPORATION

I want to bring into your notice about a fraud for which i have notified my Bank - AMEX already.
There was a charge on my credit card. The details of that transaction were:

Transaction Date: 07/30/2007
Post Date: No Additional Information
Transaction Description: GREAT FUN 800-285-5903 CT
ZOO555428 GREAT FUN
Charge: $10.99
Merchant Address: CENDANT CORPORATION
7 CAMBRIDGE DR
TRUMBULL CT 06611-4763
USA
Merchant Type: OFFICE SUPP EQUIP
Doing Business As: FAMILY FUN SAVER

I was surprised to see such charge about which i do not have any idea. So as responsible person i felt its my duty to tell the bank about it, which i did immediately.

After searching a lot about this Merchant Name and Address, what i found is that one fine day (around 2 months back), i got a card from them along with a letter just saying that (no terms and conditions mentioned) - This is your card and you can have discounts on dining in some restaurants.

Till date i never ever used that card and i was surprised as how other companies get the addresses of people and sent them such promotions.
So today i took out that card and went to there web site (mygreatfun.com/) to get the customer care no. So i called on 1-877-488-9480 . I talked to a guy who gave me his name as Patrick (do not know if it this was his real name).

I asked him as how come they can charge me and from where did they got my credit card details ?
He replied that you must have done some transaction from Orbitz and while doing that you must have selected a promotion and so you became a active member and we got the credit card details from that transaction. Then he said he will cancel this and gave me a cancellation reference no. and this will appear in next transaction. But when i stressed on, that i have not done so, he became nervous and cut the phone. I am 101 % sure that they are fraud.

Now the question is for their promotions how would they be authorised to post charges in some ones account ?
And from where they get the credit card details ?
Is not this against law ?How come they still exist if they are fraud ?This needs to be strictly taken into consideration as it can happen to any one else and such people needs to be punished harshly.
