I was there for repair of headphone jack, charging jack and side buttons and my phone was under guarantee period. They didn't resolve any of the problem and said it's working with our earphones and charger but i showed them the fault while using my charger and earphones. My earphone and charger were working in another mi phone which i also showed them, so there were no chances of being my earphone and charger faulty.
In nut and shell, i was there for a service and got nothing but only loss of my data and the tempered glass.
