[Resolved]  Samsung — Service centre in Jayanagar, Bangalore

I have been using my Samsung m30s for a year now, with no issues.
Over the month of October I've have been receiving messages about a software update. Which I did not get a chance to update due to slow internet. Last week my phone turns off and is on a boot loop, showing the Samsung logo, welcome screen and re boots again.
I wait for the charge to drain out, charged it once more upto 60% and turned it On. It's still on boot loop.
It's the issue with the software, android Operating system.
So I figure it's best to take it to a authorised Samsung service centre than a local mobile repair store.
This service centre from Jaynagar takes the phone, calls me the next day and says it's a problem with the motherboard which is not possible, we all know enough about computers that if the mother board has an issue, the phone cannot be charged nor will it turn on. So I go to the service centre to collect my phone.
Now they hand me a dead phone, which won't turn On.
I refused to collect it!
This is clearly a scam by the service technician. I gave them the phone with a software problem and they are trying to cheat me into getting a new motherboard which cost about 9, 000/-

Please help with this Issue Samsung, my phone looks like brand new. I have handled it with care, there were no physical damages. I bought it on October 13 2019 and it the problem occurred on 24th 2020.

Address of the service center : 199, 1st floor 27th cross, 7th B Jayanagar 560011
