Bought a PS5 on Facebook

I recently bought a PS5 off Facebook for $300, thinking I got a great deal. Since I hadn’t owned a console since the Xbox 360, I was excited to start gaming again. However, my excitement quickly faded when I spotted a dead roach in one of the vents. At first, I didn’t think much of it, but after disassembling the console, I found it filled with dead roaches. I cleaned and disinfected it as thoroughly as I could.

Funny enough, the Facebook listing said, “PS5 Digital Edition, really good condition, don’t really play anymore.” The console works fine, but I might disinfect everything again and possibly try to get some money back from the seller. If anyone has tips on fully disinfecting it, I’d appreciate it! Should I ask for a full refund to avoid attracting more roaches, or worry about potential long-term damage they may have caused to the PS5?
