Emailed and asked for a refund....no response in several days. I disputed the deposit charge through PayPal, and they are just stupid to deal with.....so I stopped that process and filed a CC dispute. Chase has already temporarily credited me with the amount pending final approval. My personal opinion is you need to do what you have to do to protect yourself, especially those that are up against ticking clocks. If they build the pins, then buy one at the "higher cost", but if they drag this out for more months and fail, you may lose any recourse you had.
