Mindway Nebula alternatives

I liked the device I bought one approximately a month ago and when they had a sale on refurbished I bought two more to give as gifts. There was a glitch on the site when I pourchased and completed the order it di not go through and give confirmation, so I submitted it again. I then checked my credit card immediately and saw there were two charges and contacted the company. Instead of cancelling one they still shipped both and in a polite way basically said too bad, my problem after a couple emails back and forth. I would not recommend this customer experioence. As a small business owner I would try and rectify the problem.
