Defective device and told about policy yet im not responsible for sesor failure

I bought an Iphone13 on the 8thMarch 2025 ,on the 6thApril it couldnt recognise my face i then took it back to Istore Eastgate where i bought it the inspected it and said FaceId sensor has a problem they booking it in.

So now my question is am i gonna get the repaired phone after carefully using my brand new phone for less than 8weeks ??

I asked what causes the sensor to break the Technician had no answer to that he just told me they will tel me when its back from Repairs

The reason i bought a BRAND NEW PHONE is because my phone was broken that ive been using for3years and i HATE using a phone that has been openned and fixed .little did i know i will buy a brand new IPhone and only use it for less than 2MONTHS then it become Defective and ve told they will fix and give back to me the very same device .

My phone has no scratch or dent to show to show it was well taken care of it did not even fall cause i was really gonna understand veing given a fixed phone if it was my Negligent as im told my phone is taken to technician how is sensor failure my problem that i should get a phone that has been opened and fixed by "BEST TECHNICIANS SO I WAS TOLD "?

if ever i wanted a 2nd hand phone i was gonna buy pre owned that i have no informtion about it being fixed before or whatever ....i left my phone heartbrokenly the thought of having to use a fixed phone make me even HATE IPhone i really regret taking my money buying an EXPENSIVE DEVICE hoping ill also get same standard as the value😡😡😡😡
