THEY TOOK MY PACKAGE TO USPS AND JUST LEFT IT. NO HELP WITH TRACKING NUMBERS. MY PACKAGE WAS FROM CHINA THEN SF EXPRESS THEN USPS WHO REFUSED TO DELIVER THE PACKAGE TO MY FRONT DOOR. USPS WAS GOING TO SPEND MY PACKAGE BACK TO CHINA. IT TOOK A MONTH TO GET HERE. SF EXPRESS DID NOT HELP ME AT ALL. I HAD TO GET MY PACKAGE FROM USPS BEFORE THEY SENT IT BACK.
