My credit union charged me a five dollar fee for not updating my address. Does this seem right?

I moved a few months ago and didn’t update my banking info since it was a pain and my current info is going to change soon and calling them is a tedious. They don’t allow you to change it over the internet.

So a few days ago I notice a odd fee.

So I just called and they said they are charged by the post office if they get mail returned. I find this claim spurious. And really.. Five bucks?

Has anyone had a similar thing happen and does the USPS actually charge for mail marked “return to sender”?

This is the first I have ever heard of such a nonsense charge.

After a few minutes on the phone they did reverse the charge.
