Tata Motors — ac malfunctioning

Address:

Golaghat, Assam

I bought a tata tiago car on 20/11/2017 from progoti motors, jorhat. Today the 05/01/2018 my first servicing around 1500km at progoti motors, golaghat.ac is not working properly. After few minutes air stops blowing from vents.ac makes noise. They said it's for auto cut system. But car gets hot after then. They checked ac gas its only 260. It should be around 600. They are charging for rest amount of gas. I asked for put up a complain. They said that they r forwarding to higher authority about the condition. Disgusting...
