BGASC B_A_C Claimed that I was protected because mail shipment was insured. Calabasas Internet

I Ordered $13,574 worth of junk silver ($1000 face value) from BGASC.   When shipment arrived it only had $4,072 worth of junk silver ($300 face value) in the box, $9,500 worth of silver had been stolen.  I assumed that the loss would be covered because the webpage stated that it was insured.  When I contacted BGASC they gave me the bums rush and said that they were not liable.  The Insurance mentioned in their webpage only covers BGASC from loss the consumer is just out of luck.   Copied from their webpage “Every single package we ship is sent with full shipping insurance for its time in transit. This means that in the unlikely case your package is lost or damaged while in transit, you will receive a full refund of the purchase price.” This is just not true.  I agreed in their Terms & Conditions that I would not sue them so I have no recourse.   I filled a claim with the USPS but they will only cover at the most a $5,000 lost, if the USPS pays the max amount I will still out will be $4,500.  If I had known that the shipment was not covered I would not have bought from BGASC.
