Honda Cars India Ltd. — unethical behavior

Address:

Chennai, Tamil Nadu, 600096

Sent my car honda city (Tn 14m 2927) for routine servicing at the below service station:
Capital honda
#130 & 131, perungudi indl. Estate, chennai - 600 096.

The car was picked up on 19-feb-2019 at 0930 hours from my office premises and supposed to be delivered back by 1700 hours the same day. I send my car for servicing only after confirmation from service centre that the car will be delivered back before 1700 hours, as i had to attend a critical medical case of a family member at that time.
At 1645 hours, the service station called and confirmed that my car will be delivered in another 20 mins. I again confirmed with them that in case there is any delay let me know frankly in which case i was come to the service station directly and pick up my car to able to reach my destination in time. But service centre again assured me that the car will be at my office premises by 1705 hours.
Since 1705 hours i was waiting on the road infront of my office but there was no sign of my car arriving. Finally i took a cab and went to the hospital. At 1810 hours i received a call from service station that my car is on the way and reaching shortly.
Luckily by taking the taxi i reached hospital in time for the planned medical treatment of my closed one.

Till today morning 20-feb-2019 i have still not received my car.
