I had purchased from them for the last 12 years and had no problem. However, I recently bought an electronic item and needed it returned. Amazon sided with the seller. The seller agreed to the return, e-mailed me that it received the item back and refused to refund money. Amazon knew this, had Post Office Delivery proof, and only sent protected e-mails to the seller. When this didn't work, Amazon refused to help me.
On my own I had to find out Sellers address and phone number and contact them. They claimed I wasn't in their system at all and never heard of the company that shipped it. I told them the 3 names the Corporation was registered as being under, the two addresses, and the Presidents' name. I told them I would be contacting the State Attorney's Office for fraud, US mail order fraud, and credit card fraud, etc. They hung up on me. The next day Amazon credited my charge. I will never use Amazon again. They still allow this company to sell on their site knowing they are frauds.
