Given my iphone 11 pro SERIAL NUMBER (DNPZT9X2N6Y5) for display changing. After repairing when i try to open my device its showing i phone is locked by owner and showing different person apple id.

I check with apple support team as per them the serial number of i phone which i got from the shop after repairing is different as the one i given. SIM tray number is matching with my original one but they change motherbord so serial number is different. I have the original purchase invoice also there also serial number is different.
