Pizza Hut India — Pizza Hut evading refund

Address:

560036

We have ordered for pizza on 7th Aug16 using pizza hut mobile app and cancelled the order much before it was delivered by calling pizza hut executive. Executive accepted my cancellation and informed us that the amount will be duly refund within 20 working days. Unfortunately the refund transaction did not happen even after following up Piazza hut a few times. It's more frustrating the P.H executive keep me on hold for long and then replies that someone will call back me which never happens... hence making false promises.
Wanted to know Piazza hut intention for not refunding the money. I feel that P.H is trying to evade from refunding and doesn't care to look into this issue.
Wanted to know who is the escalation point in Piazza Hut to take this complaint forward if this forum cannot resolve my issue... Thanks
