Both companies tlg great fun and tlg travelers advantage began taking 12.50 each from my bank account in June 2009 and did so thru december 2009 without any authorization. My bank said they cound not stop them since they were taking it from a debit card number.
I finally cancelled my debit card and had it reissued with a new number which is the only way I could stop them. I tried calling them several to get my money refunded without ever getting to talk to a person. Always put on hold for very long times.
Hopefully this will stop them.
