Big Bazaar / Futurebazaar / Future Retail / Hometown — Not picking up calls , kept on waiting for 90 minutes. No concern from store

For my BigBazaar order[protected]
Paid an amount of 1004.50 using future pay wallet on 29/04/21. Order was successfully placed on the BigBazaar app and was to be delivered on the same day. After not being delivered I contacted the store next day (30/4/21) and they said my payment had failed kindly call future pay customer care. Future pay customer care number had a wait time of 90 minutes and then disconnected my call. On calling again it said, wait time 40 minutes
