Delhivery — Awb[protected] not delivered

Awb no[protected] was not delivered to me…….i contacted customer care and raised the issue with them and was assured of a response within 3 days but no action or communication happened…..despite repeated reminders im still awaiting response…..and since it is a prepaid order it comes under deliberate fraud on behalf of delhivery…..pls resolve my issue at the earliest.
