Mahindra And Mahindra — Cheating in service & Poor response

Iam Dinesh Vadlapatla, my car was hitting with an accident in July 2020 and taken to "M&N Motors" Rajamundry for service. They claimed for Insurance and given a quotation. They delivered me my vehicle after 4 months in this December First week. They didn't done the work property. And more over they didn't changed the parts which were covered in insurance and taken the bill. When iam asking to rectify the complaints they are not responding about it. Iam totally Wexed for your service. Immediately take an action on them and rectify my complaints.
