Assurant return damaged device package Empty!!

Going through the same thing right now. 20 years with them. Only used the insurance a couple times. T-mobile turned off all 5 phones. I spent the day messaging them on a laptop. They told me to pay 215 to get my phones back on. I did. They told me they couldn't turn them back on and that I needed to call Assurant. Clearly I can't call so they call me. They connected me to Assurant and Assurant keeps "trying" to send me to USPS. USPS fraud department is always "closed". They all just keep hanging up on me. T-Mobile reps keep telling me I need to pay the almost $600 for  the phone to turn my service back on. Something fraudulent is going on and I am not paying. My husband is going to the store in the morning to try and talk to someone and call our lawyer. Good to know this is happening to other people. Could get a class action lawsuit. Don't want to but this is garbage!
