This is a happy blog.
My homeowner’s insurance company, CIG, made a mistake and deducted the same monthly fee twice. The company immediately put one charge back in my account. I never noticed until two weeks later, while reconciling the account.
The company sent a letter of apology offering to pay any expenses that had been incurred by the mistake and enclosed a $10 Starbucks card.
Good recovery from an inadvertent mistake. I call that recourse in my marketing book. All businesses make mistakes, how they handle them is the measure of competence.
