Tvs Motor Company — Poor quality bike and worst dealership by TVS

I purchased a TVS Sport bike from Dhiraa Motors, Virugambakkam on 26 Aug 2021.
TVS proudly advertised saying that the mileage would be around 100 to 110 kmpl but I hardly get a mileage of 55 to 60 kmpl.
Within 4 months ( bike had only reached 3000km) of purchase the clutch plate fell down on the road while I was driving. On complaining, the dealer they refused the defective condition of the bike and asked me to pay for it.
After the clutch plate was changed, oil started leaking from the bike. When I contacted the dealer regarding this, he started blaming me saying that my driving is not proper.
I have been driving for the past 30 years and have never faced such issues with any of my bikes so far.
I'm deeply distressed by the quality of the bike TVS has given and the worst service by Dhiraa motors
