Xiphias — refusing to provide necessary free service by declaring phone out of warranty on filthy grounds

Address:

Akola, Maharashtra, 444005

My self rahul awandekar from akola, i have purchases redmi4a in the september 2017, last month on 12 february 2018, my phone automatically went dead,
I surrendered my phone to authorized service center flex mobiles in akola for repairing on the same date, the receptionist took my phone asked me the problem and told me they will call me after 2hrs.
After 2hrs what they told me was shockingly unbelievable,
They told your phone's on off switch is broken and hence your phone's motherboard got damaged, and phone will be repaired out of warranty,
Gave me estimate of rs 5000 around for in warranty phone for repair.

My on off switch was intact and fully functional, apart from that how on off switch would damage motherboard of phone?
Anyone who understand little bit of electronics would understand fraud this service center is doing by replacing working parts within the phone with another parts and charging customer by earning double profit, repairing phone within warranty would not yield any thing to them, this has became a very big business since common man dose not understand much about electronics
I called customer care and sent them mails several mails but every thing is worthless, very very poor service by xiaomi nothing is happening i am very much frustrated

Either give me proof of physical damage since phone was not declare d physically damaged while they received it for repairing, later after 2h they called me and told which is not accept able or
I want xiaomi to repair my or replace my handset. Or i may have to file a petition in consumer court against service center and xiaome for malpractices
