[2023] Impossible to contact Blizzard Support

Greetings, for your specific inquiry, Blizzard Support would not be able to check the status of Competitive record which is probably why you are not reaching a point to submit a service ticket, and are being referred to our existing support articles.

To answer your question, even if you did get hit with a competitive penalty, chances are the starting suspension has likely ended by now, and you should be able to resume playing Competitive Play. When you reach your next Competitive rank update, there will be an indicator in the UI showing if you had any leaver violations in that set of matches.
