Honda 2 Wheelers India — making fool to customers

Dear honda team,
I’m devesh and i have an active 3g which was last serviced at 24th march 2018. Within 2 days of service i stated experiencing mileage issue and within week my scooter started making noise when i went to service centre of 21 honda ie in sakinaka, mumbai. That time they told its just a issue of clutch we will fix it. Next day i get a call saying so and so parts are damaged and the funny part is that before going to service centre i just showed my vehicle to local mechanic he said everything is fine with parts it’s just your clutch has a problem as same was told by our honda service centre executive. Now when i went to give my scooter for last service ie at 24th march. They had already made a billing of 3000 for replacing parts and now when i went again they are again saying same parts are broken. Same kind of issue we have encountered before. Please take a strict step.
