I bought my compost tumblers 5 years ago. Some of the parts rusted and I was unable to open it up to fill it.  I called  the customer service to get a replacement parts to fix it. I was afraid that because I didn't have the receipt or anything left of the purchase that it would be difficult to get.  The guy ask me what was wrong and when I had purchase it.  With out  hesitation he asked for my address and told me when it should get to me. I offered to pay for shipping and he said it was already included.
