Maruti Driving School — I'm complaining about Nelmangala Driving school

I joined this Driving school in March 1st week. Instructor is very careless, i have opted for 15days practical class with pick up and drop to my apartment but they delivered 13 class with poor instructions. Driving instructor is very rude and keep telling you that he will fail in DL test. He don't answer call and don't come on time and no professional behaviour. Worst experience ever.
