AVG Anti-Theft Locked out phone

Hello Raymond,
We regret for the inconvenience caused.
This procedure will work only if your device has an active cellular data/Wi-Fi connection.
Tip: In case you have disabled Wi-Fi or data connection on your phone. You can enable them by changing the SIM card again and swiping down from the top of the screen immediately after the device starts, but before the lock screen is shown. This will open the quick access menu on your phone where you can enable your connections.
If the issue persist's please write back to the email sent by the mobile support team so that they could provide you with alternative resolution.
Thank you.

I have recently changed my SIM card on my phone and it locked me out of my phone once I have restarted it today. I forgot my password and the AVG lockscreen does not contain the "Forgot my password" button. I have received a support message from the AVG support team provided with necessary suggested actions to restore my phone but none of these suggestions really helped. As for Finding my lost or stolen phone, I have tried using the "Lock" and "Unlocking" tab for my phone, however it repeatedly said "Sorry, we're unable to reach your device at this time. It may be switched off or offline. Please try again later.". Is there any other possible way for me to recover my phone? Please, AVG Team.

Hello Raymond,
Please accept our sincere and unreserved apology for any inconvenience this may have caused you. Since you have tried with the basic trouble shooting steps and it failed I have asked you to reply back to the same email sent by the mobile support team where they could provide you with the next level of instructions to resolve the issue.

That is not a proper response that I was expecting. Of course I have Wi-Fi and data. Stop sending me message templates and actually try to help me unlock my phone, please!!
