Sonalika — Dealer not sending oil pump

We are facing issue in our tractor and we went to agency their mechanics said its oil pump is not working so we ordered it but now 8-10 days over they are saying yes it is coming today or tomorrow from last 5 days.
I also mailed my problem to the head office but no response in mail also
are they even serious our work is pending from 10 days and nobody is addressing our problem.
after this i will do complain in higher authorities regarding this behavior.
