Chevrolet India — Air condition issue

Address:

Meerut, Uttar Pradesh, 250004

I have 2012 chevy cruze LTZ AT. It's air conditioning system is not working for the last 6 months. I have been sending my car to the dealer in meerut. But in first few visits their computer was out of order and later they changed some valve and took thousands of rupees but ac is still not working. Serviced the car just weeks ago, when asked for ac repair. Same answer plz wait machine not working. it is still winter. Should I wait till scorching summer comes?
