Question on Fozen Nightcrawlers?

This place where i purchase my live fishing bait, mainly nightcrawlers or mealworms, they keep em in this dorm sized refrigerator, and i always check em to see if there alive b4 i buy them and here lately there froze solid. I've told the owner of the store but he hasnt fixed the problem, but the main question i was wanting to ask is If i bout a dozen nightcrawlers that are frozen would they still be alive if i thawed em out? Cause that store is like 7 miles from home and the closest other store that sells worms is 20 plus miles away.
