This story hit me right in the feels. I paid $1600 for a older Nissan 240 when I was like 18 because I thought it was this cool little racecar. Turns out it had been totaled on a race track, had no title, and I couldn't even register the thing. I ended up selling it for something like $600 for parts just to get some cash back.
Point is, it's not the end of the world. No amount of being bitter or mad is going to fix the issue at hand. I'm sure your snake is fine, sell this enclosure, put some money away, and just order yourself something new that you can trust. People tend to think failure is the enemy, I promise you it's not, you'll learn more from this than had it ended up working out.
