Did O'Day Management Inc offer free credit monitoring?

What should I do after getting the O'Day Management Inc data breach notice?
Keep the letter and the envelope, and note the date it arrived. Freeze your credit with Equifax, Experian and TransUnion, change any passwords the notice mentions, and sign up for any free credit monitoring the letter offers. Then check whether you may have a claim.

Can I sue O'Day Management Inc over the data breach?
