Bad services and inconvenience

Courier guy should decide when will I receive my parcel which I have been awaiting since the 24th, I keep calling and on Friday I was advised that I will get my parcel Tuesday on the 29th and nothing and now I’m getting notification from the merchant that they returned the parcel after numerous times communicating back and forth. May I get my parcel ASAP as we pay for courier to get our parcels on time . Bad service and no communication even from the driver and my address states it’s a work address and I have clarity that delivery should be before 4pm. I’m so furious with Courier Guy, don’t recommend . Waybill H8S7FP
