How long does it take to get a respond about my phone number

So after my account got hacked, the phone number for it was removed, I made an alt discord to use and had to put a phone number to it after I did so it was disabled(I only had it for 3 mins) now that I have my account back I can't get put my cell phone to verify it and I can't use my discord and have 300+ notifications I cannot clear and can only use overlay on final fantasy 14 to join voice channels and nothing else I can't clear the notifications or see messages I put in a ticket for this days ago.....How long does it take for a reply from discord to fix this? I'm just trying to see if my discord is okay after being hacked
