Query: Ordered new unit and received refurbished unit.

The unit itself is ok, other than the battery was completely dead on arrival. The real problem is I ordered a new unit, on sale directly from Amazon and I was sent a refurbished unit, with the previous users home address and destination addresses still in the memory of the GPS. I finally found the phone number for Amazon, which isn't easy. They should have sent me a new unit and picked up my refurbished unit. Instead, I have to send back the unit I received, for a refund. The new units are no longer on sale, so I would have to buy a refurbished unit or pay a lot more. I said ok, then just credit me the difference of what I paid for a new one, to the price you sell a refurbished one for. Amazon said, "no". Part of my purchase price was a gift card, so, I am afraid things will get even more screwed up if I return it. I am very disappointed with Amazon.
