Email address for login is no longer working. Reverted to an old email address, and won't change

[HelloMedia]

When I set up zoom years ago I used the hi@ email address.
I then changed it to kylie@ as I had a new staff member using hi@ and I wanted to have full login myself.
Somehow it's now changed itself (ZOOM!) back to hi@ and I ca n't change it back.
I have tried to contact support and the CHAT tells me I'm not eligible for support - even though I have a paid account, which I think is outrageous! 
One of my team members has the login, however I, as the company owner, should have it. No matter how hard we try, we can't change it back to me. I have screenshots and all manner of things to share. Please help! 
p.s When I try change the Zoom account's email address to kylie@ the message I receive is that kylie@ is already registered ... however, I can't log in with that email address. Very frustrating. 
Screenshots attached. Thank you.

Things are actually going from bad to worse. I'm now being kicked off my own meetings after 40 mins, even though I have a paid account and a yearly subscription! I can't reset passwords and I can't do anything. Tomorrow I am running a full-day masterclass and I cannot operate if I'm being kicked out every 40 minutes. More frustratingly, is not being able to get SUPPORT from ZOOM!

Yes, I agree  - very frustrating. Unfortunately, I don't know the answer. I'm having a difficult time just changing the email addy in my account - & I'm the owner!! The chat bot is usually useless, the CS phone number is bot operated & of no help either ... I have contacted CS via email & haven't received any response. (Except for the time they charged me 2x & they responded they give no refunds.)

I agree - bots (on chat & phone are of no help) - so frustrating. Getting a real person in CS is impossible. Site could be WAY more user friendly. Looking for a new meeting platform ...
