I sign in and when they ask me for my credit card I put it in (mistake) then when I press continue then they charge me $60 for a 100 bits and sure they charge my account right away. My understanding was that they charge. 60 per bid and I didn't even bit anything but then I email them to refund the money and they email me back that it would take 5 working days to get it back on my account. The response was quick but the refund will take days.
