Issue With Ban

OK I lose connection to a game and ban for an hour. I quickly switch games and then come back shortly only to find that my ban time has tripled for some reason. Can someone explain why my time has triple after switch games for a short while and coming back to Halo 5. If this is a bug they need to fix this soon cause I cant play for a long time now.

You had like 29 DNFs in the last 3 days!!! Your ban should be forever!
