2 Factor Authenitication reset

I have a user who used to work for our company and had an adobe account. She had set up a phone number as a form for password reset. She left the company and came back after 2 years of being gone. She of course can't remember what that password is and she no longer has that phone (divorced, had to change numbers) I contact Adobe to get the 2FA reset to another number or taken away all together and allow password reset with email. I am told the best solution is to change the email address. Or they can delete the account and we can start over.  I find it completely ridiculous that Adobe doesn't have a better solution than to completely delete an account (which takes 30 days!!!) when the user can't access a phone number used as a 2-factor authentication for a password reset. It is almost like Adobe doesn't think that anyone would ever change their phone number. I am completely in awe of how bad this customer service is. Making someone wait 30 days to get access to the license they have paid for is unbelievable. 

Does anyone out there have a better, actual solution to this? Their answer was to just use a different email address. This is for a business email address, which can't just be changed. How many businesses can just give out a different email address to a user for 30 days? How stupid.
