Wow that's atrocious customer support. If the device is non-working then you should be able to return it for a new one. Have you tried asking for a replacement instead?
No. I didn't ask for a replacement, because I don't think this product is ready to be sold to public at all.
Once, you install the Coin app it shows the map of merchants that has had successful transactions with Coin, and it's hard to find.
Basically, this product does not work at this stage, and they are selling it as 2.0 version for $100.
I am very offended by this, and feel like this is a scam.
