Paid for a Pro account but still showing a Basic account

It has been THREE weeks and still BASIC and money has left my bank account, I have an email and an invoice showing I paid for a PRO account.  Customer service is and has been zero help with the issue.  Today, another phone call later, I get told to send the email with the invoice to them and they will fix the account.  I get an email after sending them the required/requested invoice a few hours later telling me.....

"Thanks for contacting Zoom Support. It appears this ticket has been closed. If this request still requires assistance or if you have a new issue, visit https://support.zoom.us."

ABSOLUTELY STILL NOT FIXED!!!  And this is not a problem of assigneing a user (however I did try that option as recommended) but the CS reps keep telling me they have no proof I paid for the PRO account - what am I to do to get someone who will fix this!!!!!!???????
