Bests & Worsts Reviews from Amazon

I recently received a letter advising me that my credit limit has been reduced. The reasons are from past credit card issues, and my credit score. So if you are approved watch out they will check your credit score and reduce you if you have had issues in the past the caused your credit score to drop. I call this practice unfair, not one other of me credit cards does this. I guess Amazon/GE do not like having customers with low credit scores, or customers who are trying to rebuild their credit score. Stay away from this card, it's not worth it. Unless I missed something in the fine print I never gave consent for Amazon/GE to check my credit score when ever they want. SAD, UNFAIR, and even discriminating. Wonder if I should have my lawyer look into this.
