Bigbasket.com — Bbstar membership not honoured , order not delivered

Order id : EXN[protected][protected] and order id : EXN[protected][protected] not delivered. I am bbstar member which entitles me guarantee delivery slot but bigbasket failed to deliver and are not ready to provide me acceptable resolution. After raising multiple escalation almost 5 times still bigbasket is not ready to talk or help me just ignored me . I such cases bbstar membership is not useful and it is not honored causing me stress to follow continuously with no resolution. I demand delivery today itself or bbstar membership refund.
