I am disputing the change of my flat APR to a variable APR, because I rejected the new terms you sent me and then you closed my account. I rejected the new terms, because I didn’t want a variable APR and to keep my minimum payment calculations the same. By you changing my APR to a variable rate it may violate the Fair Credit Billing Act and may violate contract laws on a closed account. I have no problems as long as my APR remains under xx.xx% and my minimum payment calculation remains the same. However, it is my understanding you can never go over xx.xx% APR unless I default, because I didn’t agree to the new terms and I still don’t agree to the new terms.
