Query: Not a tough blender

I have used this blender for three months, making fruit smoothies three or four times a week. It simply crushed and blended a mixture of fruit, liquid, and ice cubes. It worked fine until the blades broke out of the base of the pitcher. The blades are mounted in a plastic plate, which is fastened to the base of the glass pitcher. That plastic plate snapped clean from the pitcher. The motor still works fine.
