Query: poor quality control

For one of the pieces (part #4) the screw won't go into the hole. The holes in part #2 don't seem lined up right (to get the actual parts that hold up the bike to fit together part #1 won't screw in. So in the end I can't get it together.edited to add: did manage to get it together, have to have the screws only in partially and then sort of bend the stand in order to get the remaining screws to fit. So after getting it assembled it does work, but glad its on a padded carpet as it doesn't really sit flat on the floor so sort of rocks a bit.
