You and your spouse have separate charge accounts at a local department store. When you tried to use your card last week, you were told that you were over your credit limit. This puzzled you because you had paid the entire account balance several weeks ago. When the monthly statements arrived yesterday, the error was clear. The store had credited your payment to your spouse’s account. Your account was treated as over the limit, and the store charged you interest on the unpaid balance. You suspect that part of the problem is that you and your spouse use the same last name (Morales) and have similar first names (Carmen and Carmelo). Write a letter to the store requesting correction of your accounts and suggesting a way to identify your accounts so that this error does not happen again.
