"Klaviyo: Email Marketing" cannot be used, but the payment has been deducted, I want to complain

I bought an APP from SHOPIFY APP STORE. The name of the APP is “Klaviyo: Email Marketing”. When I enter the APP, the account is shown to be disabled, prompting to be reviewed. After a few days have passed, no one is reviewing. No one responded to the author’s email, so I have to complain to them.
