Query: Breaks fast!

Got one of these a couple of months ago, after about 20-25 uses, the part that does the mixing/chopping broke. To be more accurate, the black part on the bottom of the container that is turned to perform it's chopping action striped out the very short machine threads that hold it onto the blades.Forget about parts.
