I bought a LEMon a couple of years ago after reading good reviews on here. I went through the SAME condescending customer service problems. I got fed up much quicker than you and just returned mine for a refund. Took a couple of weeks after they had received it and me calling with tracking number to prove they had it before they ever refunded my money.
They should change their name from LEMon to POS stuffers!
I bought a 15lb Kitchener from Northern Tool. Great quality, steel gears and cost less than the LEMon. I would NEVER buy anything from LEM ever again!

I would strongly suggest to admin that this thread should be made a sticky or flagged for the main page of the forum so that anyone coming here would see NOT to buy a LEMon. They don't deserve any of our business.
I also bought the $99 on sale meat grinder from Northern and have run a lot of meat through it with no problems. It's not a commercial grade by any means but it works fine for my home use right now.
I hope yours is now fixed and you don't have any more problems.
