Maruti Suzuki India — non repair of vehicle for more than 112 days in the workshop

Address:

East Khasi Hills, Meghalaya, 793003

Dear Sir/Madam,
My Car Estillo Zen met with an accident on 11/12/17 and was towed to the nearest Maruti Workshop on 20.12.2017 for necessary repairs and for Maruti insurance cover and claim etc. I had submitted all the relevant papers for smooth process of the repairs and claim. But after 112 days in the workshop, I am repeated told parts have not come. (For your kind information, the workshop I am referring to is RANI MOTORS, Shillong, Meghalaya, India).
I do not understand how long will the parts be supplied after making indents because my car is a discontinued version.

112 days of wait for the parts to be supplied I think i ridiculous.
Please help to provide the indented parts at the earliest.

Regards
Mr. Bedarius Shylla
