Worst customer service. Very bad experience with a customer service.
They'are selling items back-ordered as if they actually have. After I noticed, I canceled my order and request a refund, but they don't give you clear answer. What the rep says just "Ok!". Just two letters. That's it. They didn't tell me if they actually cancelled and processed my refund. I believe requesting a charge-back is the only way. Do not buy anything from CDW. Worst online seller.
