You're definitely doing the right thing, California Girl. If you were in the buyer's shoes you'd want the seller to do something about it
It is annoying that some people don't read descriptions better, and in some cases you can't refund their money if it's just plain too unreasonable. Like once when I sold a radio that I clearly listed as not working, the buyer then complained to me because it didn't work. Now that, is totally ridiculous.
