I just purchased 35 MHs scrypt a few days ago (at 6,6 price jeje).
I did 4 separate purchases. All with credit card.
My stupid VISA card didnt work at all with UniversyPAY (the card
gateway hasflare uses). One of the steps always fail.
Well, support guys from Hashflare FIX the problems for me.
All the times. In a few hours. No questions. Only one ticket telling them my problem,
and a email back from them in a few hours with problems solved.
Not sure if they support is 24/7 (maybe not, one of the tickets was solved next day).
BUT SURE HASHFLARE SUPPORT WORKS VERY VERY WELL.
I also ve had a question for the support this weekend. It was resolved within 24 hours so everything works quite well.
