Alright, after a bit over 3 1/2 hours, finally we could get the thing working.
I have to say Rue (the Binance CSR) was great. But I think if a customer has to go through that to get ahold of their own money, the people at Binance should think long and hard about their security measures.
I spent almost a week trying to make things work. Since then my assets went down almost 20%. That and all the stress I've had to endure.
I think it's safe to say Binance will never receive another penny from me.
Thank you all for the help!

I'm glad you solved your problem finally and became able to withdraw your funds from there. But yeah I know/feel those stress and frustration during the process as I've been in that situation before while I tried withdrawing like two month before.
