Called, didn't leave a message. Can't find info on them so I called them back, blocking my number of course. Of course it's a robo answer and it does not give any company name or information what so ever. It does, however, give an option to opt out. Since I blocked my number I do not do such things. Besides, I know someone with a robo system and they generally take the number you asked them not to use and sell it to others as being a good number. So I do not hit 'opt out' and instead just use my little block box so they cannot get through again.
I would have liked to find out who this caller claims to be. If it were completely legit they would have info on their robo answering system.
