Honda 2 Wheelers India — timing and issues servicing

Address:

200/1, M.G. road, Ramchandra pur, Kolkata 7000104

I booked for servicing last 4th of june through phone and the representative said come 5th of june time 11am to 11:30am.
I came same day around 11:15am, but the problem is that around 4pm service boy said parts no available.
Before making the jobshit why don't you informed me.
When i shouting then manager arranged the parts from another work shop.
Approx 5hr i'm waiting for the bike serve. This is really rediculas.
I'm completely disappointed.
This is not 1st time every time i faced the problem.
Service centre name shah honda, 200/1 m. G. Road, kolkata 7000104.

Please take action.
