Mahindra And Mahindra — accidental service is not responding correctly against insurance cover

Address:

Allahabad, Uttar Pradesh

Sir, my car is kuv 100 next up 70ec9293. One day a truck struck my car on highway and my car damaged badly. Then i contacted to service center and firstly they charged me 2000 rupees against complaint. And then told me that they got permission from insurance company to release car but after checking it they told me that there are some more problem like balancing, black smoke, break shoe problem, and charged me approx. 10000 rupees against it. And 2700 rupees against procees fee...
Sir, please help me to get rid off it. If i have to pay this much then why i paid insurance fee for car.
This is ridiculous about service center, they had made me fool before also while free service.
