I had this happen in 2018 and had no trouble getting my account back. The support agent requested pictures of me with documents -- front of credit card used as payment method + passport -- and then disabled 2FA on my account.
I provided the payment details, the date and amount of the last transaction as text, a screenshot of my bank statement of the transaction, 2 forms of ID (passport & driver's license), and a photo of my face next to both ID's on January 23rd. I replied again on February 7th with the most recent date of my transaction and the amount paid.
No response.
The tough lesson to learn is always to deploy from a source code repository.
It sucks to lose your stuff, but if you follow best practices it will make you a better developer/architect and things like this will only become minor inconveniences.
I had to lose months of hard work for similar reasons to learn this lesson.
Redeploying the site and even saving all the files uploaded to the site are both relatively trivial. The deploy is almost entirely automated and I can still login to my root user panel, download any uploaded files, and transfer them over to the newly deployed site - so I'm only experiencing minor data loss. (eg. the DateUploaded for files will be lost and I don't care enough to try and back that up to restore it)
Hopefully I do everything right and prevent link rot. Thankfully I'm the sole user of my file host so nobody else is losing any data.
