Query: LEGO'S?

This kit and the Helicopter kit is the worse Lego building sets we have ever gotten.There are so many warped pieces that it can not even be put together.The Helicopter goes together but does not stay.They are very hard to build and impossible to play with as you are always putting them back together.Very disappointed and i do not know how to get my money back with the box destroyed and pieces are loose.I can not believe the poor quality of these kits.It is not something you expect from Tonka or LEGO.
