I pre-ordered the bigger (originally 25Mh/s) Viper on March 29th. Paid £1,635.00 with a bank transfer. Later on, I asked for it to be downgraded, which they did by marking the first order as completed and opening a new one for the Viper (50Mh/s) on the 22nd of May. I need only to pay £26.99 for that order to be fully paid.

I don't have the C.C. protection (having paid with a bank transfer) and no idea to which date counts towards a cancellation but most likely soon out at 50% -still better than most I concede-. Because I paid with a bank transfer I'm thinking my best chance is to wait for them to fail the due date so I can start a small claims court case.
What files should I be saving to backup a small claims court case?


Edit: I'm assuming due date as the date they mention on their latest update; "...before shipment (which will begin somewhere from the 15th-31st of July)..." Legally If they e-mail that as the latest update that's the one we can point to?
