Pizza Hut India — order cancelled but amount not credited back to my credit card

Address:

Mumbai City, Maharashtra, 400080

I had ordered online (Over the internet) for 2 veg. Pizza's (1 veggie supreme and 1 exotica) on 8th october 2017. The order number is 9206562.

The total amount including gst was rs. 578.20, which i paid by credit card. But since the store where the order got registered was far away from place where i stay, the delivery boy cancelled the order and i was told that the amount will be credited back to my credit card within 48 hours.

But till now i haven't got the refund of amount (Rs. 578.20).

Giving below the details of store where the order got registered:
Store address: ground floor 14-16 1st floor 116-117 e wing, latif park, mira road, mumbai
Store no: +[protected].

The mobile number of the delivery boy is [protected].

Please look into the matter and do the needful.

Thanks in advance.
