Indian Oil Corporation [IOC] — Gas Cylinder 10 days still not delivered

I made a lpg booking through Indane app on 11/02/2022 and till date 21/02/2022 not received my cylinder. I called the agency they are saying they will not deliver the cylinder as they are not our primary distributor, but as per app we can select the nearest distributor for booking. So if they don't want to give service and deliver why they are not cancelling the order, but instead they invoice the order.
