Bests & Worsts Reviews from Amazon

Update, I message their Facebook page asking for help to fix my useless axel, and instead of answering or helping me, they blocked me. What kind of company does that? (see pics) Dissatisfied. The hex caps are too small to fit on the wheel axel, so I cannot attach the wheels. The poor packaging was not enough to protect the tank during shipping, and there is a large dent in the side of the tank. I am missing a bunch of nuts and bolts needed for assembly. There is minimal instructions on how to use and assemble this, and there is no company information or additional online instructional materials available. I am worried to even attempt to use this.
