KTM Sportmotorcycle — coolant not sustaining in my 2017 duke 390

Address:	Mysore, Karnataka, 570016
Website:	Ktm.in

I have recently purchased new ktm duke 390 on 14th apr 2017 and it has coolant leakage issue from may 2017 and there is no trace of leakage to be found on the bike. Ktm dealer at mysore has failed miserably in determining solution to the leakage problem.
I have been visiting them every now and then and still the issue persists. Recently on 20th july they changed the oil seal of the bike as they told that the coolant is mixing with engine oil.
After the change still the issue is not resolved. I rode about 180km and the coolant has disappeared.
Kindly i request ktm to resolve the issue or exchange the bike as it's still in warranty.
