JPMorgan Chase & Co. Credit Card Complaint

JPMorgan Chase & Co. Credit card department,

APR or interest rate California

Chase bank raised my interest rate from - to - on my current balance for purchases and any future purchases without notice to me on -/-/16. I tried calling the company who first stated it was done after review of my credit rating. Yet, when I told them my credit rating was steadily improved over the years since I have no late charges or over-balance issues, they stated they could do it periodically without notice to me. I then discovered that they are applying my payments which are over the minimum to the lower interest balance transfer amount before the higher interest balance that they raised without notice to me, so they can get more money from me. I want to opt out of this change and be refunded all interest charged over the - from -/-/16 and I will stop using the card and just pay off my balance. This is unfair for them to raise my interest rate with no reason and without notice to me. I would have been treated better if I was a delinquent borrower/consumer. I should have received notice to have the opportunity to opt out the change.
