Query: Couldn't put Blender together again

This blender really worked great until I had to take it apart to wash it. You're supposed to be able to unscrew the bottom to get it really clean, right? Once I washed it and put it back together, the bottom piece would no longer fit into the spinning part of the base. I took it apart serveral times, trying to figure out what was wrong, and had others try it. None of us could. We called and they offered to send out another part, but they never did. they said if the new part didn't work we'd have to bring it to a repair center (an hour's drive away). I waited too long for the part, then it was too late to return it to Amazon. Then our new puppy chewed up the box. I am so mad I wasted 50 dollars (at that time) on this blender I used for just a couple days. I bought a smoothie maker at walmart for 13 dollars.
