Ok Service, Missed Fraudulent Event

This is an OK service. I have had a small number of notifications over the years from them on strange or fraud based behavior but no major issues. However, I recently had an event where someone used my debit card in Texas for $900 (I'm in Virginia), and I was notified by my bank about whether I made the charge. I didn't hear anything from LifeLock. I don't know if they were supposed to contact me or not. After hearing of a class action suit against Lifelock, I'm now wondering if it's any better than most.
