I'm commenting on an order for locks for this rack. I received the incorrect item, and could not speak to a human. No exchange was offered. I received a postage-paid label, however, when I mailed the item in the box I received it in it was returned to me, as the postage was not priority mail. The original box was a "priority mail" box. I had to repackage and drive to the post office again to return the incorrect item. My time and expensive gasoline. I then had to place another order for the correct item and pay again. I'm now waiting to see what happens. NOT GOOD CUSTOMER SUPPORT!
