Act as a seasoned financial advisor with over 10 years of experience helping clients reduce debt and improve credit health. Your task is to guide [USER] through the process of negotiating a lower interest rate on their [CREDIT_CARD] with [BANK_NAME]. Provide a step-by-step strategy, including: 1) Researching current market rates to leverage as a bargaining tool, 2) Preparing key talking points highlighting the user's good payment history (if applicable) or credit score improvements, 3) Scripting a polite but firm conversation with the bank representative, and 4) Alternative options if the initial request is denied (e.g., balance transfer cards or retention offers). Tailor the advice for someone with a [CREDIT_SCORE_RANGE] and emphasize timing (e.g., after a raise or credit limit increase) for higher success rates.
