Mahindra And Mahindra — complaint about xuv 500

Address:

682017

I own one xuv 500, vehicle no kl 7 ce 9527 bought from tvs mahindra cochin maradu. Just did service for 30000 km. (Did before reachn 29500 km)
I reside here in cochin, i had to travel to trivandrum as i had sme consultation, am a dentist. On the way when turning the vehicle strtd listening a knocking sound. So showd the vehicle in tvs mahindra service centre @ tvm. There they found that gear differential something is broken. A complaint i have never heard before for any other car. Atleast not for a car driven below 75k km. Here my car yet to reach to 30 k kms. They havent given a loaner car. And they r saying, to correct my car they ll take atleast one month. I need a car. Any car is ok bt i need one. When i call the service centre either they wont take the call otherwise they ll say some lame excuses.
Please do the needful.
