So I was sending a Galaxy S6 Edge in for repairs for overheating and it was brand new. Samsung's Plano, Texas 3rd party company wrote down it had liquid damage and the warranty was then voided by Samsung. The device never touched liquid in the first place. Then it also came with rooted access from Team Win Recovery. I didn't remember it being there with Super User when I reseted the phone multiple times when I was trying to ensure it was a hardware issue. I called their direct support and they noted the account and the rep didn't buy the liquid damage on the motherboard either because he said it shouldn't turn on properly with that. Then he said he was sending me to his upper level of support, but transferred me to T-Mobile and didn't say a word so I was under the assumption it was Samsung and then it caused more headaches. What do I do because there is clear negligence on Samsung's partners' end. I never root my phones either. I am furious because the phone is still problematic.
