CAN'T LOGIN TO PRO ACCOUNT

I HAVE A PRO ACCOUNT. I CAN'T LOG INTO IT. IT KEEPS TELLING ME TO USE ANOTHER METHOD. NOTHING ELSE WORKS. I'VE SUBMITTED A TICKET OER 24 HOURS AGO. NO RESPONSE. I HAVEA A RECURRING MEETING NOW WITHOUT A HOST. I HAVE NO IDEA WHAT'S HAPPENING IN THE MEETING. NO ONE WILL HELP ME!!!! ANYONE IS ABLE TO JOIN THE MEETING AND CAN SHARE THEIR SCREEN AND I'M WORRIED THE MEETING WILL BE TAKEN OVER BY SOMEONE  WITH AN AGENDA.
