Hi, my name is (Your Name). I have been a cardholder with your company for the last (number) years. My account is in good standing and I would like to continue using it. However, I would like you to consider giving me a lower interest rate on this account or I may switch to a card with a better rate.

Record the name of the person to whom you spoke, the date, your interest rate and then a date six months later when you can make your request again. If the person refuses to give you a lower rate, try again the next day to reach someone more helpful. After successfully lowering your interest rate, wait six months and ask again.
