Wonderful Car with Pathetic Aftersales

I am driving a Tata Tigor XZO Diesel for the past 3.5 years. It is a wonderful machine and robust machine and was available at an exciting price point. It came with many bells and whistles, unlike the Maruti Suzuki Swift Dzire Diesel at the time when we bought it. I bought it from Concorde Tata - which was the company-owned dealership. They had an outlet in Malad West and a Service Centre in Andheri East. The first and second free service of the vehicle was done at Concorde Andheri Authorized Service Centre and were fabulous. Then the nightmare began. Concorde Andheri closed down - there was one more Authorized Service Centre titled Richard Garage which was pathetic. I gave the car for servicing and the service centre was short-staffed. I visited the centre 3 times and every time there was someone new to talk to - the old employees had left their jobs. I was zapped and surprised. After a long wait of a month - they could manage to service the car and deliver and that too without washing. I thought this was one of a kind experience and decided to go with some different authorized service centre the next time. My next 2 services were with Banai Auto - which was very good - professional and polite. But unfortunately - Banai Auto also closed down leaving me with one option - Wasan Motors at Kandivli West. Here the horror began - Wasan Motors' workmen damaged the car by bruising it against a wall or another car. The front left fender was damaged completely and the dent continued until the front bumper. This was noticed by me upon delivery. The person sanitizing the vehicle accepted that this happened at their end and asked me to speak to the service manager. The service manager asked me to take the car home and bring it after a few days as there are too many cars at the moment. Upon my refusal to take the car - he tried to show the JOB Card and said the damage was at the time of delivery itself. BUT THE JOB CARD DID NOT HAVE ANY MENTION OF ANY SUCH DAMAGE. The service executive then realizing his folly, tried pressurising me to claim my zero depreciation insurance for the same. How can I as a customer make a claim on my zero depreciation insurance for an error on the part of the authorized service center? I have brought this issue up on Twitter and also emailed on the customer care email ids of Tata Motors and the Wasan Motors Group. It has been more than 3 days but I haven't heard from them. I sincerely feel that Tata Motors company should do something about their service centers which are limited in numbers and perhaps choked with the increasing sales of Tata passenger vehicles. Every customer at the service center was having some or other issue with the service quality, delivery, and costs. This is not sustainable in the longer run. I have had various brands of cars - Maruti, Hyundai, Tata, Jeep, Skoda, etc and this by far is the worst service experience.
