Rentomojo — Booked an AC 1 ton , later decided. Cancel but no revert from the rentomojo

Booked an AC 1 ton on 4th sep. Informed on the chat support for cancellation they said it is canceled and you will get a confirmation within 24hours on email. However it has been 3 days since and there’s no update on my cancellation neither on the refund. Their chat support doesn’t work. No reply on emails. Have been sending them emails daily but no responses. You cannot reach their chat representative at this point of time. It is frustrating.
