I was given a Christmas gift of 50 dollars that was redeemable through CashStar. Chose Applebees as my redeem choice through CashStar and had vouchers printed that had a number on it called a challenge key code. Went to Applebees to redeem and the challenge key is not recognized as valid! Called and corresponded with Cash Star and they cannot find my email nor codes that show I have these vouchers! They steal your money, don't give a crap about your loss. Challenge keys do not work, this piece of paper with the key codes on them have not been out of my possession! POS rip off company. Do not use them. Dishonest thieves! Enclosed are proof of purchase photos which you can see the challenge code, I'm not worried, the codes don't work.
