Big Bazaar / Futurebazaar / Future Retail / Hometown — Haven't received the item or the refund

Hello,
I have ordered two items from future pay on 8/05/2021, where one of the item was cancelled at the last moment and its status says that the amount of the item is refunded but I haven't received the amount on my wallet. And for the second product the status is showing as delivered but I haven't received the product yet on 11/05/2021. And there is no way to contact as the toll free number provided on the app is not connecting.
Now I just want to know what to do next??
