Refusal to all recovery of account

Well you are going to have to keep working with them ot attempt an account take over ayyempt after 3 tries

2 things it's best to do the report with a previously connected device that used the account

Also if you are failing at account recovery they are looking at original info on the account not changes literally stuff only the owner should know

These are set in stone set by privacy and data laws

I've given every bit of information they requested (DoB,location etc) short of the password (which is why I'm trying to recover the account to begin with). Am about to fire up my oldest laptop I could find so hopefully that might have some connection/info but doubt it.

At this stage I'm going to have to create a new account as I've been trying for the past 4days (so 8 attempts) and no luck

As you.been already told they can only give it to the accoumt owner

If you are failing it us because you are failing at core info that MUST match

And no they can't tell you what you are getting wrong

That would give you unlimited chances to phish

Sorry to hear that your account recovery form has been rejected.
When that happens, these are the options available for you:
https://support.microsoft.com/account-billing/a...

Please note that no one here including Microsoft support can send password reset links or modify/change account details for security reasons

thing is with microsoft, you cannot use the recovery form for an account with 2fa enabled, you will need to contact support directly as there is no online way of doing this, usually microsoft refuses to touch an account with 2fa on as even they cannot retrieve codes for the account.
