hi
you have done all the correct things - and you could have basis for a lawsuit, based on the negligence of verizon in which your personal information was accessed. but you would need to show damages - for instance, if your information is used in some sort of ID theft. hopefully, this will not happen. but you should consider talking with a lawyer in your area to discuss the merits. keep in mind, unfortunately, the mere fact that someone accessed your information would be be cause for action without the damages.
