My ordered food was not delivered and the courier boy denied at the last moment, why did not he said while placing the order.. And said i won't come to deliver the order and forced me to cancel... After cancellation zomato chat support told the amount will be credited within 4-5 days but after 4 days are over they denied for return. What is going on.. How they can keep the amount.. Plz help and resolve this issue and return my amount
