From an outsider reading in.. it sounds like..
someones brother bought some mining equipment. It was paid for, but not delivered for 4 months. During that time a delivery and or refund was discussed.
Now 4 months on, the refund is off the table ??
Is that the issue pretty much ?
You forgot the part where shipping information was never given and also the part where there is a refund to be given as well as the proceeds from the equipment auction in progress.
