IOS – Is it possible to delete a customer review that contains wrong information

You can't use an existing Apple ID and then enroll it into the store.

The "none" option only exists for new accounts as a one-time (or limited count) event for that device thanks to scammers and people that manipulate app store ratings with factory reviews and paid downloads.

You can usually make a brand new Apple ID following these steps:

It's generally a bigger pain to have two Apple ID, so I would encourage you to not set up a new ID just to avoid the temporary delay of getting a legitimate address and card for temporary use.

Once you have your account verified, you can use store credit for just about everything on the store.

I don't think there's an automated system, I once requested two expedited reviews in a row (due to my own improper testing), and got both accepted.

So no, no firm rule, but they'll probably look at your history when deciding, and your reason for asking for an expedited review.
