Honda Cars India Ltd. — Regarding spare order cancellation

Address:

Malappuram, Kerala, 676517

I have booked a steering rod for my honda brio at apco honda malappuram and gave an advance of rs2000/-. They told me that it will take more than 10 days for the spare to arrive. Meeanwhile a local workshop man solved my problem and i no longer needs the spare..
So on the third i contacted the showroom to cancel the booking, the said i cannot cancel the booking since it already despatched. And they now are demanding the spare cost as well as the service chrge for fitting the rod, do i have no right to cancel the booking??? please help me.
