Mahindra And Mahindra — About Service

My self Milind R Shirsath. I have brought XUV W10 model register no. is MH 05 CM 7857.
There are some clutch related and Hill decent control fail issues in my car.
I visit the Global galleria service center in thane and told the same things to concern authorized person (Mr. Irfan). He said vehicle clutch plate is burnt and need to be replaced. I said Ok. but clutch plate was not available till today and there is no response to any call from service center.
About the Hill decent control fail issues i was told to the concern authorized person when last service done. But the same issue not sort out yet.
Then on 20th march 2017 I dropped my vehicle at your authorized service center G3 Motors Dombivali . And told above mentioned issues to G3 Motors employee Mr. Swapnil. His Mechanic and he checked the vehicle and assured me to solve the same problem. That time i doesn't get any quotation about expenditure. Then I dropped my Vehicle there. After Four days later(on 23rd March 2017) I got my Vehicle. with Rs.41176/- bill and Very dusty and muddy condition of exterior and interiors.
On 24th March 2017 (Just 15 to 16 hours after repairing) when i am going to Out of station Hill decent control fail issues arise and Lock the all buttons of Drivers side door. It was so torched.
I immediately called the Mr. Swapnil of G3 Motors, Dombivali. He told me to bring vehicle on Monday(27th March).Meanwhile your other customer care employee (Mob No.[protected]) called me about performance of vehicle after repairing. I told her the problems of vehicle. She told me to bring the vehicle on Sunday(26th March) at 10.30 AM for repairing and meet to Mr. Yatin. Yesterday I went to service station and meet to Mr. Yatin. Again he checked the vehicle and told me Vehicle has some wiring issues and his service station doesn't have any Mechanic and Electrician on Sunday. and he will pick up the vehicle tomorrow and solve the issue and drop it on same day. because on Tuesday there is Gudhi Padava.
If your service person not available on Sunday why unnecessary told me to bring the vehicle.That time I didn't have any choice so came back. Today service station person pick up the vehicle at morning around 11 AM. In whole day there is no respond from service station about repairing progress of my vehicle. around 8 PM i called to Mr. Swapnil and asking about vehicle but he can not give satisfactory answers.

Sir If You understand the Whole above condition, where is my fault? In 5-6 days your authorized service station doesn't solve the issues and not giving satisfactory solution how should i TRUST on your Authorized service station.
Tomorrow is Gudhi Padawa (The New Year Of our Marathi Person) on this day people buy new vehicle or Etc. and my vehicle is in your service station. Why should I suffer because of your mistake .
So I request you to kindly look in to the matter and give me satisfactory result as soon as possible. And also suggest me other reliable (If Have) service station for my vehicle.
If not please suggest me where i can sell the My XUV 5OO.
