I'd say that it's definitely not you - it's them. Sounds like the whole thing was poorly organized. If you really want to volunteer somewhere, there are lots of organizations that need help and in some communities there are even agencies that match people with volunteer opportunities. Just contact groups you think you might be interested in.
Don't let one set back discourage you.
