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???
I believed the coupons expired on the 16th, and now it's a week later. It was posted up and down this thread so you'll probably get no sympathy. Most tried to sell their coupons last minute.
