I can't verify my account, since I'm getting an error 500.

I opened a trial account using my new work email, however, they already had a DB business account and I wasn't made aware of that.   So we cancelled the trial account, deleted the account and I am now trying to change the existing email to my new business email in my work's existing profile.  I have successfully added it but I cannot verify.  I have had DB Support trying to help.  I have tried all the different browsers, used an incognito window, tried on my iPhone, tried a totally different computer - NOTHING!!  I constantly get an Error (500) - Something went wrong.  Don't worry, your files are still safe and the Dropbox team has been notified.  Check out our Status Page to see if there is a known incident, our Help Center and Forums for help, or head back to home.

I have cleared history, cleared cache, done all the steps Support advised except send them a recording which my work will not authorize.  This is extremely frustrating.  I need to change this email to move forward with my work tasks.  HELP!!
