Delhivery — False Update and Parcel Undelivered

My parcel was due to be delivered on 20th June but customer got a message for cancelling the delivery. Though the customer dint share any otp for cancellation still the parcel was cancelled and still not delivered. False updates are being given that call was placed to customer but customer got no calls. This is the 4th time im facing this issue with Delhivery courier. Awb no[protected]. Its so much harassing for me and my customer to face this issue continuously.
