Bad service

I would like to share my experience with the South African Post Office service delivery and the lack of communication thereafter. I received my parcel on the 15th of March at the Fairland Post Office and upon collection the parcel was empty and it had been cut open. Parcel contained 3 phones, iPhone 7plus, Samsung S7 edge and Asus Smartphone. I completed the form given to me for lost items and submitted affidavits and receipts of the phones to the manager but until now there has been no communication regarding the process of recovering my parcel. I am quite gutted that this is the kind of service we receive from the national postal service. I have had to call countless times but never got any clear clarification
