Maansarovar Honda — cbr 250r headlight switch problem

Address:

Chennai, Tamil Nadu, 600091

I have bought cbr250r in 2017 from the first service my headlight switch was problem i have told many times but they didnt consider at that time they are doing but after that it was not working properly and in last service also i told but they just cleaned that switch and given after 10 days again same problem. So today i went (12 feb 2019) i have showed the problem now they are telling that u have to change the full assemble set cost 2500/- how is that possible it is not my mistake because start of the first service it is a problem or if it is not good means last time itself they need to tell to change the switch box but they didnt. So i need to solve the problem or whatever action taking also i m ok but it has to work...
