I went to use my 3 unused coupons today from the Bitmain Hash speed issue and found out that they expired.
What a crock of crap.
If they dont give me my coupons back or the equal bitcoin I will not purchase their products anymore.
Has anyone else had this happen???
you are the first that admitted to letting this happen. many gave them away sold them or used them. no one else confessed to letting them die.
I admire you for admitting this to us.
