Was anyone able to get back into their phone after AIG locked and erased it?

AIG has locked and erased my iPhone. No one can help turn it back on. My phone is essentially a doorstop now. I have not been able to use it since 2/8/23. I wanted to schedule an appointment to repair my phone screen. I mistakenly hit "File a Claim", realized it was the wrong selection, and hit the "back" button. At that point, my card was removed from my apple wallet, phone was locked and erased. I have been unable to use my phone since that time. AIG sent the following message about a hour ago: Thank you for reaching out to us in regards to your AppleCare+ Theft and Loss claim. At this time after reviewing your claim and the information that is connected to it, it would appear that your claim has already been closed on our end. That being the case, we at AIG her no control over how long it takes for a device to be unlocked once the claim has been canceled. I would advise reaching out to Apple for assistance with having your device restored if the standard attempts to troubleshoot the problem have not resulted in its continued functioning.

I've contacted Apple support seerveral times. No one will help and it is extremely frustrating.
