Verification - no 6 digit code received in Hotmail

This problem happened last year when I returned to the US.  I lost access to Dropbox on my Macbook Air and iPhone,and I have my login email and password but Dropbox is just not forwarding the verification code to my hotmail account. Last summer, I had a similar problem and managed to get someone on the phone at Dropbox to help restore it. 

This is an older (not regularly used) account that I have valuable items stored in.  The recovery questionnaire apparently wanted ALL the questions answered correctly. 

My real name is on the account. I know I can name plenty of files that are inside the Dropbox account. I have my passport and ID, and there are photos of myself in that Dropbox account (which match my ID). 

If I can speak again by phone with someone, I should be able to regain access. I can pay for one of the services if that is a barrier.

I just really want to regain access. (I also want to finally turn off 2-step verification once and for all. I thought I'd done that last summer but here it is blocking me again. Hotmail seems to not like verification codes. 

This happened now because I bought a new iPhone recently and all my saved passwords failed to port over to the new phone.
