4 games is a pretty small sample size. Sometimes awful stuff happens in streaks. Not saying it doesn't go beyond these games but just keep that in mind when deciding how you talk about your experiences, especially over a short period of time.
Also the key is to report all of these people doing these things, ignore them reporting you for anything you didn't do or that isn't against the rules, and move on. You don't need anyone else in your game to report them for the report to matter either. I see so many games at plat+ (I watch a lot of streams) where someone does something very much against the rules and literally no one reports them. Then all those people who failed to report the issues wonder why there's so much awful behavior. Hopefully you're reporting all these issues and encouraging anyone you know who plays to do the same, but so many people definitely are not and it really matters.
