I have had the same experience more than once, and have come to the same conclusion as Colorado Cowboy. DIY. Many game processors operate on the communal theory. If they estimate that you brought in 75 pounds of boneless meat, you will get back 75 pounds of boneless meat. Who's meat it might be is anybody's guess. Chances are very slim that you will get back "your" meat, unless you know the processor. One of the better taxidermists in Casper advised me against using some of the processors there for just that reason. I have a couple of the new generation ice chests that will hold ice for an extended period. I use block ice (crushed is useless for long term), and stack my boned bagged meat on the blocks of ice.
When using dry ice for transport, I made a plywood shelf for each ice chest that fits on the inside lip in the ice chests. Cut a few 1.5" holes with a holesaw, sand, and finish with 2-4 coats of polyurethane. After I pack the meat. I put in the shelf, and put dry ice on the shelf (wrapped in newspaper). I have hauled meat from Colorado (850 miles), and Wyoming (1,200) miles using both methods without any meat spoilage, and without having to add any extra dry ice. Sometimes, I do have to drain and add a couple of extra blocks if I am using the "wet" method.
