Royal Enfield — royal enfield 350es, complaint for wrong service and damage

Address:

Kamrup Metropolitan, Assam

I purchased a royal enfield 350es bike on 12th of april, 2019. After 4 days i went for my first free servicing at jorhat, assam, acharya singh dealer. Fuel was leaking from the carborator, and their servicing was very unpleasant which led to complete damage and they sent the bike putting on some fevi quick on it.
How can i replace my damaged carborator as i purchased the bike from shahila exposition, v. I. P road, sixmile, chandan nagar, ghy-22.
Kindly respond to my problem as soon as possible it's urgent.
