BEST BUY SAMSUNG GALAXY S6 SELLS DEFECTIVE PHONES OMAHA Nebraska

I bought a samsung galaxy s6 from best buy and to my knowledge if anything happens to the phone it will get replaced.

I even took out a service protection on it. but now for four months I'm having nothing but trouble with it. It will not start up. cannot make phone calls. best buy said as long as it has mfg. warranty on it they will do nothing and if they did, I would have to pay another $150.00 on top of the $800.00 I already paid for it. So I sent it to the mfg. two times and now they want me to send it back to see if they can fix it. I told them just give me another phone, and they said they would have to check it out again. for $800.00 they should just replace it. that will be a month and a half without a phone.Should of bought a iphone.
