His history and reputation is all you need. If you can't access your funds, I highly recommend Dave. He worked wonders for me and others. He has had so many opportunities to just take funds and run, killing his reputation for a quick payday but each and every time he comes through and gets the funds out of the locked wallet, takes his cut and provides you back the password.
Whatever route you take, good luck with your locked funds, it's a tough spot to be in.
Thanks for your comment.
Yes it's frustrating indeed to get locked out funds this way. Hope will be able to access them again at some point.
I will see which route to take. I just wish more details were available from Dave in order to fully trust the service.
Will see what to do, thanks for wishing me luck anyway.
