Data Tech Store failed to ship product I ordered for overnight delivery. After repeated attempts, both phone and email, to reach Data Tech Store, I finally reached a store representative on the phone (days after my product was scheduled to arrive). I was told the product hadn't shipped so I cancelled the order and requested confirmation. No confirmation ever came and, despite canceling, the product arrived some days later. My biggest complaint is that Data Tech Store will not respond to either phone messages or emails (I have left a number of each). I've found other similar complaints online about Data Tech Store. Watch out! Don't get screwed like I did.
