They absolutely have the right to vent their frustration and I honestly didn't look at the situation from the pov that the op was trying to compromise.that's a great point. It just seems like it's a huge enough issue to where they are really unhappy with the choice they made. It's one thing to get the phone, try it out, return it, and then complain , but to buy it, try it, decide to keep it even though you still aren't happy , and then complain just doesn't make sense to me. After a week of trying to compromise if I'm not happy whatever it is goes back, but I get that we all aren't the same and deal with things differently.
I totally agree with your last statement. People do that a lot and it's super annoying.
