Send it back but make sure you are not stuck paying postage. I got one from ebay that was the same way. The seller's insurance told him not to get it returned. He refunded my money and I kept the machine which I used for parts. Machines were not meant to endure such treatment. Mine also had no packing/padding and the flimsy box was crushed beyond recognition. When you bid on a machine, send the seller a notice how you want it shipped if you are to buy it. If they answer in the affirmative, bid on it. I have bought 8 machines via ebay, one total destruction, one slightly damaged all due to poor packing.
