Hero Motocorp — Fuel pump issue

I have bought hero xpulse 200R just 5months and facing fuel.pump issue from one month.At present i was stuck in middle of highway .Eventough i am maintaining above 2 litres of petrol in my tank as suggested by dealer facing this trouble.Now i am almost full tank capacity.The service people also had 2nd service for this bike and not yet resolved and simply gave return .The very next while questioned related to this problem they were not in position to answer at all and simply blamed unavailability of new fuel pump.Even tough main dealer from panjagutta responded they wanted my bike to be presence now iam stuck in between of journey.I am dissatisfied with the bike performance and service with hero staff.
