I have another Vercel account with another email address, with the sign in method being the OTP code sent to the account's email address

When I try to log in I don't receive the OTP code to the email address. I have tried multiple times. The email account is not the issue, since I do get other Vercel emails like the billing emails.

I filled the "Account recovery and appeals" form as suggested by the Vercel docs, twice, but a whole week has gone by since the last time I filled it (case #01576209) and hadn't had a response

I know the email address I am trying to use is the titular of the account, and I know the account exists since Vercel keeps sending me the receipt emails
