2 Quest 2 and 2 controllers not working in one week!

I've had so many issues with the quest 2 it's crazy. My left controller would only flash fast and not connect so I bought a new one. A day later the headset had purple and pink lines in it until it went black. Couldn't get it straight afer hours on  chat with Meta. So I bought another one 2 days ago. The left controller quit on it and now it's got the pink and purple lines and went black. So I have 2 useless games and a bunch more money in it for nothing. I hope someone knows how to fix them.  I can't see anything on the screens to do anything.  Meta better fix it or I'm done with it! I was boxing both times when they quit.
