Tata Motors — Disappointing experience within one month

I've purchase Tata tiago NRG XZA recently from Jagdish Motors Dewas naka indore.
Even at the time of delivering car, chaos was created but finally the solved and for the sake of mind got my car delivered.
In my first service today, they denied for car drop facility. However, it was highly committed from their end at very first meeting itself. When it comes to execution, all their so called commitment failed which is very disheartening..
