This is more of a legal question for a paralegal or attorney. Can a credit card company lower a consumer credit card limit when the consumer has been a loyal customer for three years, never been late, was a victim of credit card fraud but yet paid the minimum credit card monthly interest payments after an internal fraud credit dispute was ruled in favor of the merchant, and paid the fraudulent charges in full while preparing to file changes and lawsuit? If you can respond to facts, it would be greatly appreciated. Thank you all.
