Hi everyone, I got a cultus from master motor engineers in October last year. Since it was winter, didn't use the ac. Now, the car has been driven 4800km and I turned on the ac but it doesn't work. I went to master motors and they said there's some leakage and want to charge 4000rs for fixing it. They say the warranty only covers ac up till 1000km. Anyone has any experience? How can this be? Any help would be great!
