Maruti Suzuki India — Service-delivery

Yesterday, my swift diesel car was entrusted with Indus Motor Co Ltd Thevara Kochi for 10000 km service with one complaint -oil warning light glowing.Assured to deliver at 3 pm.None called be back.When I contacted at 3.30pm it was informed that vehicle will be ready by 5.30pm.By 5 pm they informed that the charges will be Rs.7600 and the car will be delivered by 5.30pm at my office 3 km away from the service centre.By 6.30 they informed that the car is not in running condition.Had they informed me of the same I could have reached home early.Now, at night I had to make other means to reach my home some 30 km away.
Is this the kind of service offered by the company for such not a small cost? A local workshop is more dependable, i think. Thereafter, till now they have not contacted me.This really a deficiency in service.
