On Feb 26th I placed an order with Dell.com and selected Bitcoin for the payment option. When I hit the button to place the order, I was told the transaction could not be processed, but my Coinbase account  had shown that it had sent the Bitcoin. The following morning i received an email from Dell.com saying that they had received my payment , and asked for the order details. I provided the details, and asked them to create the order. I waited another day, and still no order had been created. I tried calling customer support, and not a single person could offer me any help. after two hours, not only was I not ever transferred to anybody who could speak proper English, but not a single person was able to offer any help what so ever. On March 4th, 5 days later, I finally received assistance from Coinbase, I received an email from Dell.com saying that they were going to send me a refund check. Now Bitcoin had gone upp $100 dollars by this point, so it was obvious what they were trying to pull. I responded saying that i wanted my refund to be sent in Bitcoin. The next day I finally received an email saying that a Bitcoin refund had been initiated, and that i would not receive my Bitcoin for another 5 business days. So this entire ordeal will have ended up tying my Bitcoin up for 2 weeks. I would not advise ever doing business with Dell,  and would not use Coinbase to process any purchases made online.
