Terrible SAPO International Mail Centre

I have had an International Parcel sent to me via USPS. USPS tracking shows that the parcel left US s****s on the 14th January. I have tried going to the Post Office but no one can help me track this parcel down. JIMC could not assist either all they say is that there is a massive backlog, but this situation hasn't changed since March. The customer service email address was a complete waste of time they say their turn-around time is 48hrs, I'm still waiting for a response a good month and a half later. Last time I checked SAPO was a "POST" office, which deals with sending and receiving "POST". I find this really unacceptable that I have to wait so ****** long for a First Class Priority Letter.
