Xiaomi India — Charger not working/Misbehave by Service center

Hi

I have bought a new MI note 3 phone in June 2016 from flipkart. But in a month, mobile charger stopped working.

I went to Mi service center Gurgaon to change the charger but they said currently chargers are not in stock and come after one month.
I asked till time, how will i charge my phone. They said its not their headache and purchase some other charger from market.

Such a poor response from MI service center. Why should i bought a new charger when i have already paid the money on while purchasing a mobile.
