Query: leaky and uncomfortable

I baught this tub for my daughter. I was not very happy with this tub the middle where it snaps together leaks every time I use it. And the most aggravating thing about it is the tub is not comfortable even with the use of the sling. Every time I use it the section where you are supposed to snap it together leaves red marks on my 5 month olds bottom and it hurts her. That hard solid plastic sticking up there is not good for a baby's bottom.
