Query: If you want to be injured, buy this cart

I received this cart a few months ago, and have used it exactly three times. All three times it was used to pull around about 20 pounds of supplies. And because Quik Cart is also advertised that it "supports up to 250-pounds, and may be used as a seat or stepstool", I also used it as a seat ONCE, placing my humungous 150 pound bulk on the seat/lid. Within 20 minutes, the entire front section of the Quik Cart's plastic box supports broke, spilling me onto the ground.Now, my main concern here is: what if I had been using this thing as a "stepstool", as it states it is safe to do for those under 250 pounds? I could have been SEVERELY injured, and I am 100 pounds UNDER Quik Box's maximum weight rating...
