Complaint / review text:
Macys credit department is famous for ruining people's credit scores. They add on bogus fees in 'error', then charge late fees for not paying 'error' fees, then report customers to credit bureau. They also report 30 days late for payments received 1 day after due date. They have some nonsensical explanation about 30 days 'representing' a billing cycle, so if the cycle is 21 days, then on day 22 you are 30 days late.
Do not ever use macy's store credit card. They will ruin your credit even if you think you pay on time. Many people who have had their credit ruined by macy's.
If Macy's knocks your credit, then all credit card interest rates go up if you have any other credit cards. I am not certain how this benefits Macy's, but you can bet that there is a profit motive or it would not be such a frequent practice. Whatever they have going on it is most likely legal yet morally reprehensible and most certainly motivated by profit.
