A story about being kindly helped by customer support

The other day, I had an issue with an order, so I called Amazon customer support.
My order history said "undeliverable" and instructed me to "please call customer support."
When it comes to Amazon, I have an image of their customer support being poor.
I've had times in the past where I didn't get a reply to email inquiries, so that image is strong, and I often see similar opinions on social media.

Because of that, I was very reluctant to call. However, since it was a credit card payment, I wanted to handle it properly, so I braced myself and made the call.

There were three things I wanted to ask.

1. Will the order be canceled, and how will the refund be processed?

2. It says there is stock, so is it okay to reorder?

3. Why was the delivery impossible?

I didn't want to complain; I just wanted to know the cause and how to handle it moving forward.
However, sometimes support staff don't understand that intent, and it's painful to be overwhelmed by an attitude of "we handled things properly, so you are the one at fault."
Before making the call, I felt like my stomach was being squeezed tight.

The person who answered was a woman.
When I gave her my account name, she immediately checked the error details. (Wow, that was fast.)

I asked my questions one by one.
The cause was that part of the address was missing. Since the zip code was correct, it seems they had been able to handle it until then, but the delivery person this time marked it as undeliverable because part of the address was missing.

The support representative was as kind and gentle as a police officer dealing with a lost child.

Me: "Thank you for your kindness."
Rep: "No, thank you for your patience, and I apologize for the trouble."
Me: "Not at all, it was my oversight."
Rep: "I appreciate that. Thank you for your cooperation."

We both hung up the phone as if we were bowing to each other and walking backward.

In the end, I realized that no matter where you go, it depends on the person you're dealing with. It's the same at shops, city halls, hospitals, everywhere.
Even though I know that in my head, I forget it immediately.
As a true Japanese person, I don't have a culture of tipping, but I genuinely wanted to give her a tip. Maybe 3 dollars? No, would that be stingy...

I wish there was a system to rate customer support interactions.
I would give this person 5 stars without hesitation.
Even if it is just their job, I truly hope that "people who are kind" are rewarded.

Postscript.
Prejudice is not good.
