I work phone service for an auto insurance company. A woman just called in, mad because she didn’t see her “discount” for taking her mother off the policy from back in January. I did the research and sure enough, mom got her own policy and we never updated her status on this one. Customer was so insistant that I correct the error that I did so… effective the date the other policy was bound. When I came back from hold I told her I’d corrected our error. She fairly crowed with delight that we’d messed up and she’d been right.
Her righteous tone ended abruptly when I told her the backdated, increased billing. If you’d just been quiet about it, you’d have saved money. The last agent probably broke protocol and left mom active because it would have meant an increase. Squeaky wheel gets the grease!
