Honda 2 Wheelers India — about new activa 5g

Hello
Bought a new activa 5g on 20th july 2018 from om sai automobiles sv road malad west mumbai
The vehicle had some problem since day 1
Not taking self start and the engine stops when the vehicle is slowed down.
Told the dealer about it and he said ride it for 10-15 kms and it’ll be fixed.
But it didn’t work and had to give it for servicing.
The service guy said the scooty has some defect.
It means the dealer had given me defective piece
When i complained he started lying and abusing.
Don’t know his name but this guy is a fraud.
Where can i complaint to get his licensed cancelled??
