Bigbasket.com — non receipt of item ordered and paid for

I am a regular with big basket. I loved to transact and scored their service a stellar rating as i ordered (On 24/12/2017) my most recent delivery request of christmas cake and some sweet and puffs for the folks housekeeping my bunglow in our absence in jubilee hills, hyderabad, telengana. Out of the three items ordered the puff order was cancelled due to unavailability (Very un-bb like, normally 'out of stock' is indicated); the packet of tiffany toffee arrived on 25th dec'17 around the later part of the expected delivery schedule (5-7:30pm). The christmas cake has not been delivered till now
