Maruti Suzuki India — not getting any response from maruti. taking my complaint for granted..

Address:	Mumbai City, Maharashtra, 400016
Website:	Consumercomplaints.in

Dear sir/ma’am,
I am sending so many mails but noone is responding but only ignoring. This is to make you aware that i have submitted my car n keys to mr. Rahul bamne as instructed by mr. Ranjeet pandey (Kalina workshop) on 15.01.2018.
Today is the 5th day my car is with you all and till now i hav not received any kind of response. Not even tried to call me back seems lik you all are least interested. If this is the matter then fine even i have all the legal documents to deal with you all.
My problems are getting worse rather then getting it solved.
Everytime they polish my car and give me back. Now i am fedup of this prob. I cannot bare the problem more.
Spending 10lakhs for such a defective piece i don’t find it worth.
I used to trust maruti but now i don’t trust you at all. This is the way you’ll treat your customers if this is the case then even we customers has the rights to go to court with all the legal documents and proof.
I request you to provide me with a fresh new piece of maruti suzuki dzire. This faulty piece i m not goin to accept at all. I request you all to kindly look into the matter and help me with the the appropriate solution as soon as possible.
Hope you take my complaint seriously and do the needful.
Waiting for your positive response.
Thanking you
Warm regards,
Raunak uday dhuru.
