I had checked with myTVS for AC Servicing of my Tata Manza car.
Upon inspection I was informed that the AC assembly Evaporator has to be replaced which costed ~ Rs. 7000.
To replace the same, I was informed it requires to remove and refit the Dashboard, for which the charges were Rs. 4000 + GST.
While I agreed to go for the same, they had done a shoddy job of fixing the Dash board. The media player is not fixed properly and is protruding outside.
When reached out to the Service Advisor, he informed that all his technicians are busy.
Now he has stopped responding to my calls.
