In order to sue them, you have to know where they are located.  Do you even what what a Class Action Lawsuit is?

It's a scam they will offer you something or another for free, then ask you to give up a credit card number to cover shipping and handling. They are using an app, that hides their real number so it becomes harder to trace. They probably aren't in Florida more than likely another country.

Keeps calling my cell .

Caller said she was calling about life alert and asked if I could hear her. I told her no and hung up. This is a scam to get you to say yes which they record and then charge stuff to your phone number. You then get a call telling you to pay by bank draft or be
sued. If  a caller asks if you can hear them HANG UP.

Report said they will ask you a question... " can you hear me okay?" Record you saying "yes" and then use that to charge you for some service!!!! Illegal, immoral, and must be shut down. Hope you all end up in prison.
