Vespa — Starting problem

Our vespa was not starting sometimes.we gave vespa to workshop in Kakinada.Its about 10 days they are not responding they are saying that the parts are not available.If the parts are not available then why you launched vespa.Without availablity of spare parts, why your company was there.Is your company is only for advertisements?we will wait for only few days if the problem was not rectified we will go to consumer court.
