I am a ladies driver, i send my car for repairing on insurance on 8 november 2019 when i came on 16 november 2019, i found my car in very dirty condition, my car battery and radio is not working and staff member refused to do anything, they also rejected my rs. 1000 coupon and said only rs. 500 can be used
The attitude of of staff members are also so rude. They also has not done denting and painting of my car which is mentioned in the bill
