I can't access my email in order to get the 6-digit security code. What can I do?

Does anybody know how long it is until somebody emails you usually? I know I’m coming across incredibly inpatient, I’ve just been sitting here for hours trying to figure out what I can do to no avail. It’s after 3:00am and I haven’t been able to sleep as I’ve read every post here and the consensus seems to be that I will not get my photos and videos back. I have mobile numbers listed on my account, know my old password up until 4 hours ago (at this point I’m wondering how my new Dropbox password did not work. I feel like there was only one box and didn’t ask to confirm it, which is why I think it was a typo. Is there a certain number of password login attempts before it shuts you out? I will sit here and put in every typo combination I can possibly think of I if it won’t lock me out. I probably sound ridiculous (and extremely irresponsible for not having another backup), but these files are absolutely everything to me and I thought I was storing them in the safest place. My email was set up through outlook and because I’ve tried to log in to many times it has blocked me out (I’m trying to get access back but it’s just an automated form that keeps saying I don’t have enough information, despite providing all the information I can). There’s nobody I can speak to there either. There’s nobody I can speak to here and I’m just feeling so overwhelmed. Is there any chance of accessing it with my mobile number verification and emergency codes? Is it worth purchasing a business plan to have the option to talk to somebody on the phone? Would that actually make a difference, or would it still just be - no email, no access?
Is there anybody that deals with the technical side of things, I can prove in so many other ways that this is my account with my files. I think I’m in shock. I’ve been telling everyone how great it’s been using Dropbox, and have genuinely been so impressed with how it works - but this is heart breaking.
