Even though they had my correct address on file, they shipped my item to the wrong address. Customer service was useless, as they repeatedly said it was delivered to my door. When I finally tracked down the package myself, I found the toner cartridge to be defective. I shipped it back, as instructed. I never received a credit from them. Thankfully, I purchased through PayPal, and PayPal has agreed to refund my purchase price, even though the seller would not. Never, never deal with these people!
