Samsung — Harassment at samsung customer care center bangalore, refusing to replace faulty charger

Address:

sampige road malleshwaram bangalore

I bought samsung galaxy m31 on 30/mar/21, charger stopped working since early july. on 12 aug 21 i found out i can get replacement within 6 months period and visited samsung service center in bangalore, initially the woman at the door refused to believe charger is not working, she tried to send me off saying you upgrade the software and charger will work. I made her connect to the plugpoint and showed it is not working and i need replacement.
The service person said unless software is upgraded they refuse to give me new charger, first they said 45 min, they took another 45 min and in the end the phone was not working, they were unable to connect it to
system, they said it will take another 2 hrs to repeat the process, Such incompetence and it sounds idiotic for replacing a charger why should they service my phone and download software without my consent.
Aslo guys tell me all data might get wiped out. Why should I loose my data for a replacement of a charger? they refuse to replace the charger
i had to come back wasting 3 hrs and my energy. Such bunch of ###.
