Who do i talk to about ranked

because I got suspended and can’t play ranked for a very unfair reason and I would like to get that fixed.

I would give up.
If you got suspended after tons of disconnections they are not going to help you.
Even if you think that it is not your fault.

Unfortunately all disconnections and game crashes counts as leaving the match and will be penalized appropriately. The game server has no way to discern a legitimate disconnection or game crash from one that is forcefully caused by a dishonest player to bypass leaver penalties. You can learn about this policy here:

Well that sucks my game crashed and they wont even care, wonderful.

If you wish to troubleshoot why your game crashed players like myself or Blizzard Support Agents can help with that. Please specify details of the crash, or start with these steps.

i fixed my crashing error now but that was the reason why I got suspended.
