WhatsApp owns its account restrictions and review decisions. Polymorfa support cannot unlock a banned account or promise that a review will succeed. Use the review option in WhatsApp when it is offered for your account.
Tell Polymorfa support when the restriction appeared and share a reviewed screenshot of the warning if needed. We can investigate the connection and relevant Polymorfa errors, separately from WhatsApp's decision. Do not send registration codes or pay someone claiming a guaranteed unban. See WhatsApp account bans.
