Cannot receive confirmation code

Hello,

I am very frustrated of meta support but I'm not giving up.

Here is my context :
I logged out of my account, I forgot my password so I tried to ask a confirmation code to be sent to my email but I don't receive it. I started dealing with Meta helpdesk on the 7th april through case number #*** and it's still not resolved. I have been trying to get my case resolved with them for a month and I'm very tired not getting my problem fixed.

The problem I'm facing :
- Cannot receive 2FA code to my email account, it is impossible to get it myself.
- The META support sending me confirmation codes (8 DIGITS instead of 6 !) that will not work (I keep telling them it doesn't work but they persist with it).

Steps I'm following :
- Land on auth.meta.com
- Click on "continue with email" and enter email
- On "Check your email" step it asks me to enter a confirmation code, cannot receive it. I'm stuck there.

What I cannot do as a workaround :
- I cannot use facebook, my account is unrelated
- I cannot used instagram, my account is unrelated but share the same email. It tells me I would need to create another account linked with instagram but that has a different email.

Many times, the support sent me confirmation codes or 2FA codes I don't understand, they are 8 digits ? So despite my attempts to enter them I get limited to 6 digits. Of course it doesn't work.

(Translation : Paula sends me a code to use of 8 digits.)

(Translation : Login Failure. Your email or password is incorrect.)

Other thing that I tried with those codes I received : Put them as password. Not working.

What I've done on my side :
Looked thoroughly in my spams, junks and nothing in my email.
Tried different browser on desktop + phone
Tried private mode on browser to clear cache

What I dealt with the support which FAIL to help me:

- Case number: #***
> Verified with the support my account by telling them my HW Device, Lasts 4 numbers of my credit card and username.
Ticket is apparently closed because the issue is being handled on the second ticket.

- Case number: #***
> Did the dumb first steps like checking if it was not my browser or spams to give them confirmation it is not on my side...
> Verified my identity with an official ID Card
> Been stuck in a loophole of telling them I need to enter a 6 digits code but they keep sending me 8 digits ones.

What I think would be the best solution :

- Tell me how to proceed so I can send you a different email that you could change on my account so I can receive my future confirmation codes
- Meta redeem my account's value in a gift card (equal or more) so I can enjoy playing again on a different account
- Change my password manually and send it to me however this won't fix my email verification code problem

I would be looking for a way to communicate in PMs if possible for a better communication between us, that would be extremely appreciated because I am wasting so much time with Meta.
