Sorry to hear about the lost controller. Based upon your statement there is no hope of finding yours through the shipping company. Hopefully there was enough insurance on your package to cover everything including the 500. Based on several bad experiences, if you don’t buy insurance for the full replacement value of everything shipped then you might as well not buy any. There was a controller show up on eBay recently that may be from a shipping receiver center. Asking 2.5 to 3x of it’s used value.
