How to remove Activation Lock on iPhone purchased from an Apple authorized store in Vietnam?
I bought an Iphone 17 from an Apple authorized store in Vietnam in October 2025. A few days ago, specifically on December 1, due to my ignorance, I accidentally logged in a public apple id to my device. As a result, my device was activated Activation Lock (My screen showed Iphone Locked to owner).
Then I submitted a complaint via: https://alsupport.apple.com, I correctly selected the For a personally owned device section, I filled in all the information along with the proof invoice with the serial number of the device written on it. After waiting for about 2 days, I received a rejection from Apple, saying that they would not be able to consider additional requests or documents related to this device.
What should I do now?
