Sir,
I own a maruti swift lxi 2012 model petrol. Its four door window opening handle just fall off from the panel. I got to the service station to fix it, they replied that they dont have the spare and agreed to arrange the parts within two days but its almost 4 months past still havent arranged the parts. Cant open the window without the handle. So please do the need full.
