Query: Beware of cheep parts

I ordered this blender for protine shakes and pureeing flax seeds. For the blenders first use I pureed the seeds and it did a good job. A few days later I used the machine for the second time when I made some protine shakes. While the mixture was blending the goats milk leaked out the bottom of the container all over the machine. There was no way of tightening the plastic nut on the bottom of the container. I sent the blender back to amazon 2 weeks ago and still have not received my credited gift card. The old osterizer I received as a wedding gift 20 years ago with it's cracked container does a better job.
