MyTVS — All round dissatisfied and worst service in all through my life

I had given my I20 car for a general service in MyTVS off sharjapura road, Bengaluru. Despite exorbitant bill, rear break drum got interchanged with some spurious part from another vehicle (that side is completely rusted), wiper bolt cover was not replaced after changing the blades similarly was a part near front windshield, wheels are not freely rotating(when I complained about it they said they will send a mechanic to look into it but never did). Whatever been touched in service seem to be fixed incorrectly. This is my first experience with TVS as I used to go to Hyundai authorized service centers all the time.

I feel a road side mechanic would have done a better job. I didn't mind to complain but after a long ride from Bengaluru to Chennai recently I really feel the vehicle was in much better condition prior to service. My vehicle number is KA-51-Z-6824.
