For your information:
"All sales are final" for private customers is against European Law, even in Switzerland! This is NO B2B sale!
The good thing here: There is a law enforcement treaty between EU and Switzerland.

BTW: I asked Mr. Anselmi before your "production" status message applied. He asked me if I would change my mind when he offers me an "twince an avalon bitfury upgrade" and gave me time for the decision + I won't loose my right for refund. I decided for refund 1 week ago and I still got no confirmation nor the refund at my bank account..
