Apple India — Iphone 12 Mini

Address: Cochin

I have bought a new Iphone 12 mini and its face id is not working from the 15th day. (its showing error as - there is an issue with face id, please contact customer care).

I visited Apple care 4 times in last 2 months and they just reset the phone and give back to me and the same issue is repeating again in few days.
4th time also they have restored the phone and given back to me with out repairing or solving the issue.

I am sick and tired of this iphone and the no support they provide and i am unable to use this phone.
