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???
Someone already said it expired last week so I think.
That's BS. Had I realized they were going to expire before I could mine more coin to purchase more I would have opted for the refund in BTC. Bitmain better make this right or I will also go to a competitor. Customer service and delivery times are what set the hardware manufacturers apart.
