Had enough

I had an S6 edge for a month. It didn't work. Eventually replaced it. The replacement had a problem with the battery. Took it in, another week to get a replacement. All this time I have to contact the call centre to find out what is happening with the phone! Get the 3rd replacement and have the same battery problem. Phone Shaun. He tells me he'll get back to me, wada wada wada, still waiting for his call. I am not waiting another week for a new phone. What is Samsung going to do about this or can I now give up, tell Samsung to shove it and go to Iphone? I have now had enough of waiting for people to get back to me, wasting my phone bill following up and getting phones that don't work!
