It might be a good idear to start a new thread instead of bumping a 4 year old one with a question that's not related (nor equal to) the question initially asked in said thread. It's called necroposting, and by doing this, you'll probably get a much lower response rate.
This being said, you didn't provide nearly enough information to give any meaningfull answer... Are you still able to log in? Do you see transaction history? Did you try to contact their support dept? Address, transaction id's,.... Without any extra information, other people won't have a clue as to what might have happened either.
So, what i would propose you do is:
1) stop posting in this thread
2) contact block.io support
3) if they don't answer, create a NEW thread with sufficient background info
4) realise that we are not block.io support staff... We don't have access to your account, we are unable to fysically give you your funds back... We might give you some pointers and some tips tough (if we have a gut feeling of what might have gone wrong)
I, for one, have not looked at this service in 4 years... My input might not be that good... I didn't even know they still existed.... But maybe by following above steps, somebody who used their service recently could chip in.
