Query: SPT Model 101

I bought this product, & followed all directions about cleaning, etc. It made ice very quickly, but when left alone, the ice melted!I called Customer Service and was told that he unit does not keep the ice cold, but the ice must be placed in a freezer! All the other ice makers I have had keep the ice cold. I returned the unit with a negative comment.
