Asked about extending warranty asked if I wanted to speak to a warranty specialist, replied "Yes" call went dead after that. Tried to call back nobody picked up
If asked to respond in a yes or no answer from an unknown number, NEVER SAY yes, bec you're not responding to the question being asked. Any yes answer is tagged to another question that's going to be used as you agreeing to some service you know nothing about or used to somehow get money from you.
Say nothing, hang up!!
I got a call from 937-365-2255 today , 4/4/2017. it rang once and hung up. When I called it back I got a recording telling to push '1' to get on a 'do not call list'. I figured if I pushed 1 I'd be putting myself on their list.
