Modern Gen Auto Failed to fulfill an order Fort Worth TX

I placed an order on ebay - #03-08047-00038, for two items, ID number 253405775562 and , ID number 253405759836. When I failed to receive a shipping confirmation I sent a message through ebay inquiring as whether or not the items shipped. That was sent on the 28th. I received a response stating that the items were shipped on the 28th via USPS. In that notice I was provided a tracking number which appeared to resemble a UPS tracking number!

On the 30th I received ONE package VIA UPS, with one of the two items.  

I followed up with ebay and was told they won’t do anything until January 6th but the problem is that both items have been assigned the same tracking number so it shows that the order has been shipped when in fact I have only received one of the items!

In my extensive research I have learned that this company forfieted their corporate status in November of 2021. I found indications that they are now in a holding company wich I thought was a very reputable corvette parts supplier but I have contacted them and failed to get a response.
