Poor sportsmanship??

I recently have been aborting games on chess.com. However, matchmaking took a turn as it took so much longer to matchmake as usual. I played the same person twice without rematching, and played people 400 points below my rating. However, I got no warning whatsoever, and no message, so am I flagged with poor sportsmanship? Chess.com didn't say anything, and I don't think I have poor sportsmanship. Can matchmaking return to normal? I've been loyal for over a year with a diamond membership, and I've been instrumental to banning @XumiChessMk3 and alternates.

Thanks!

It takes 5 hours to get someone within the range

You will get paired up quickly if the set the range within -100 or -50 and set the upper limit +400.
