I had tried to cancel an order with ATC Supply immediately after placing, after it was discovered the item was labeled incorrectly and would not work. They refused to cancel - sent the item and requested I mark the package 'Return to Sender' so I would get a refund. I did as they asked, and they never sent the refund. Now, I'm out the item and the money. They are dishonest and deceitful. I would recommend others stay away from these criminals.
