Zoom Car India Pvt Ltd - Refund was not even initiated within promised time

Refund was not even initiated within promised time by zoom car and they have violated their own policy by saying error is there in system. Have spoken to ** diff ppl who gave all false dates for refund and finally one rude agent spoke and asked me directly why do u call so many times after informing refund will initiate after **st May. I can assure you can check call records and none said that. They are making fool of me. they have a refund policy of *-** days which is past and I have attached all proofs with booking ID
