I originally placed an order for a part they sell on Amazon. The tracking number for it was showing a message that was very confusing, so I emailed them. Customer service responded to me within the hour on both email and livechat. They said that USPS seemed to be having trouble on their end, so I contacted the postal office and was told the address was wrong, but it wasn't their fault. Jenna bared through all my emails and happily refunded me the package when after the product warranty expired, the item was finally returned to sender. They even offered me a small discount on my next purchase. I'll definitely look up Zeetron again when I buy from Amazon.
