Network locked / Fraudulent device given
I am from India. I purchased an iPhone Xs last year for my personal use from a local vendor. The phone worked perfectly for a year and suddenly stopped working in May. The network is locked and I cannot use it besides as a dummy phone. While searching for the reason and after the visit to the Apple store, I found out that my phone is from the USA and locked by AT&T. When I sent a request for unlocking to AT&T, it came back as "Device is flagged for fraud". I am not sure what else I can do? I tried to go back to the vendor but due to lockdown his shop was closed and recently I got to know that he is absconding. I found out that he has duped many people as every day someone is coming to the shop searching for him. I paid nearly 50K or approx $600 for this phone and now I am left with nothing. I have never been to the USA and do not know how the Fraud has been committed in the USA with a device from the India. Can someone guide in correct direct and assist me with unlocking my iPhone would be very helpful. The phone has costed me huge money and after the jobloss I do not power to purchase a new device. Please Please Help Me!!!
