Hindustan Petroleum Corporation [HPCL] — Non delivery of LPG gas cylinder

The HP gas cylinder has not been delivered to my house even after calling and complaining to the person responsible for delivering. He keeps on asking for another few hours again and again. We don't have enough gas to cook food and have to order online. I called on the helpline no:[protected] and the person told me that the matter will be resolved within 5 days. Are we supposed to order the food for my whole family for 5 days? Why are we paying for gas cylinders if we have to order food online? Please look into this matter and resolve it as soon as possible.
