got an amazon fire tablet for xmas. Wi-fi only. Have router, but have never personally used it. So contacted the tech help for the router and was directed to a lovely gentleman from India who told me the problem getting the router to work was in the computer. Hey, what do I know. I am so tech ignorant i'm still in the 1900's. After a bit of him coaching me to do this and do that, which I gladly did since he was the router's representative, I began to wonder--esp when he began wanting $$. To him. So ended session and contacted the router's telephone help. Who assured me that the nice man was a scammer. And that they could repair any damage he did to the computer--for a price. So I hung up. And still can't use my pretty tablet. And changed all my passwords. And feel my faith in humanity ebbing further away. So--how can you tell if the helpful people who answer the "help" are truly helpers or scammers?
