My younger brother is on our cell plan with my wife and I. His ex girlfriend had her phone stolen so we felt bad for her and got her an spankin' new iPhone 7 on our plan. She had been paying us $50 a month for almost a year. They broke up and I asked for the phone back. She kept it and put it on Straight Talk. It still shows up as a line on our account. Short of finding her and taking it can I report the phone lost/stolen to Verizon and have it black listed? Or am I going to eat the rest of the $300 left on the device payments? I know, I shouldn't have, lesson learned.
