Why is droid turbo 2 dropping calls?

[D4S]

I have got my droid turbo 2 in February and a green line came through the screen. I got my replacement phone and everytime I would be in a call, about 50 seconds in, the call would drop. No matter where i was the call would drop. I have gotten 3 more repl

I think both the Droid Turbo 2 and Verizon are [removal required by the Verizon Wireless Terms of Service] now because all they are doing is sending me new phones with the same problems.
