Come on, they're Elderly, call them and explain, they'll make good on it.
One day in Wal-Mart I noticed all the bottles of "Mr and Mrs T" bloody mary mix were filled with, well, something clear. Water? Vodka? Some bloody mary flavored stuff that's clear, to make some cocktail I've not heard of? I finally just took one, opened it up, and took a taste. It was water. Talk about a QC problem! I took the opened bottle to Customer Service and explained what was up, I think they fixed it.
Doesn't fix that Mr and Mrs T bloody mary mix is pretty insipid without a good shot of rooster sauce though.
The point is, screw-ups happen.
