Hero Electric Optima Plus — non cooperation at service station

Dear Sir ,
My daughter Farha Tarannum purchased a Hero electric optima plus,
against bill no.863, dt ,16/05/2009,receipt no.1070 from
B-13/3,Asafali road,New Delhi-110002,tel:23250139.It had been taken
for all the services required,according to the given time table but
the service/Maintenance Record page had never been filled by the
authority at service centre.On 3rd service even the coupon had not
been filled.
After 6 months in early November09, the vehicle stopped abruptly and
carried to the workshop.The attend told us that wiring is short
circuited and melted, you have over roded it and I have corrected the
wiring.After that it is stopping every time.Some one in the workshop
suggested that its overload switch is not working and we ask them to
change.They told us that the switch was not in the stock you have to
come some time later.After that they are doing nothing and telling us
to use the scooty without the switch.Three months have been passed in
this way the vehicle is standing idle, who is responsible?We have
suffered very much .Please help us.Thanks

Yours
Habib ur Rehman
