Kindly submit a support ticket under the section "Lost Device/Locked out via 2FA" on the PlayXchange Support Portal.
You will need to submit your details on the PlayXchange (Name, DOB and address) and include documentation that verifies that. You may be required to submit more than one piece of documentation to have all of this information verified.
Please also describe what has happened that may have caused you to lose access (eg. deleted 2fa app, lost your device etc)
Please also include a selfie of you holding the photo ID so we can verify it is the same person trying to access your account, and include your mobile phone number including country code that is capable of receiving SMS.
We will then manually reset your account and have a new verification code sent via SMS to you. You will continue verifying via SMS so please alert us if your number is lost or changed.
