I ordered some deck drain from DK Hardware and the website said each 5' section included 8 couplers and 4 end adapters. When I received the order there was only ONE (1) coupler and ZERO end adapters! I called and talked to the "Customer sales rep" and he was difficult. He grudgingly agreed to send me 4 couplers and 2 end adapters (which I told him that is all I really needed for my project) but had to get management to approve it. When I did get the shipment, there was only 2 couplers and 1 end adapter! I just got off the phone and told the same guy that they were short by 2 couplers and 1 end adapter. He would not agree to send me what was agreed on and said he would have to have his manager call me back. I am now a very angry customer and writing this review. It would have cost them very little to satisfy me and make me a happy customer, but they refused to do that. DK Hardware's customer service is HORRIBLE. I would not do business with them at all. Find another hardware store to get what ever it is you need. Amazon sells almost anything you need!
