Maruti Suzuki India — Car misuse and lack of explanation

Address:

maruti suzuki, kothari compund, thane, maharashtra

I had sent my car for body repair work at manpada thane service centre. upon recieving the car, i noticed that my car has been driven 31 km despite my home being just 5km away from the centre. I had informed this to the Regional head as well as the workshop head and have not recieved a satisfactory explanation from their end. They say that car has been driven for parking purposes . This is an absolute shame on MS brand that they use and give foolish explanations. How is 20km for parking purpose justified?
