pathetic service

I am tracking my parcel , and no one can tell or share the pin . I've sent out the parcel from Pretoria to Cape Town on the 29th April .Collected from home to be delivered to a locker . On the 2nd May received an email that the courier attempted to contact the receiver ( my sister ) and could not get hold of , to attempt again delivery on Monday 05th May talking about high rick area., thought to deliver to a locker. On Monday 06th May , I tracked the shipment in the morning after 7am , its out for delivery at 16h00 in the afternoon no delivery yet . when I called , its been delivered system needs to change the status , but where is the pin, no pin yet system must change the status to get the pin to a locker . What kind of service is this . I called twice *** phone is dropped on my ears . They dont know when am i getting the pin to the locker but its delivered . All I need is the parcel , to wait another day its crazy .
