Pizza Hut India — order no. 9063069 cancelled but money not refunded

Address:

Hyderabad, Andhra Pradesh, 500032

I order a pizza online at pizza hut on 16sep17 and selected my address from the automated pull down menu. The order was diverted to a wrong location and was immediately cancelled. However, i was advised the money would be credited back within 21 days. Today is 27oct17 (More than a 1.5 months) and my money is still not credited to my card. Their customer service is least helpful and uninformed. Nobody knows what's happening except offering apologies. I need my money back immediately.
