Dear John: I’m hoping you can help me resolve an issue with Allstate that I am unable to resolve on my own.

My wife and I were encouraged to take a defensive driving class to receive a discount that would lower our monthly insurance costs.

Upon completion of the course, I sent the certificates to my Allstate agent, and he, in turn, sent them internally to Allstate, telling me we would receive a discount that would lower our six-month premium by $100.77.

I was speaking to my agent a couple of weeks ago about when that discount expires, only to learn that I wasn’t, and hadn’t been, receiving the discount at all the entire time.

The agent said when he called Allstate, they said they made an internal note on my account (never notifying me or agent) stating it was unable to see the certifications legibly so then they weren’t able to make any changes owed to me going back to the original date of 12/4/17. The best they could do was backdate the discount one month.

I think its really lousy that Allstate, a company with a $34 billion market capitalization, is unable to give me the proper discount I’m owed. Given that it’s been 2 ¹/₂ years, it’s a touch over $500. I’m hoping you are able to help me get the proper discount and have Allstate do the right thing. A.K.

Dear A.K.: As you know, I called Allstate for you, and the company is fixing the problem.

You said: “I just got off the phone with my Allstate agent, and he informed me that Allstate is going to make things right going back to the original date they’re supposed to in 2017. I’m still waiting to find out if I will be credited on my account or if I will be cut a check.

“As you could imagine, they wanted me to reach out to you right away to let you know that they’re finally doing the right thing. I can’t thank you enough for your help. It’s a shame that an individual customer is unable to get fair results, and they only do the right thing when they receive one phone call from you — and they suddenly realize they’d rather not have bad publicity and risk alienating multiple potential future clients. Keep fighting the good fight.”

OK, Allstate, you did the right thing. A lot of your customers and potential ones will be feeling better about insuring with you. And, by the way, I like your commercials with that guy sitting in the middle of the road, or do you have the duck or the soldiers?

Anyway, it was nice doing business with you.

Dear John: Regarding the recent letter about Key Food in the Bronx, I think what the 82-year-old is saying is that the employees at the supermarket scan their own points card when you check out, not that they steal points from customers’ actual card. A.I.

Dear A.I.: If that’s what they were doing, I bet they’ve stopped now that I’ve called the store manager.

A free turkey because you have enough points — for most people — isn’t worth losing their jobs.

And everyone who relies on points or other benefits from store purchases should ask the cashier if they’ve been applied and then look at your receipt.

If there’s a discrepancy, call the store manager and it won’t happen again to you or anyone else.
