You sent it 6 days ago to your savings. Then it's in your savings.
Now, 6 days later, you want to take it out. So you can.
Click on the blue link "Balance: 49.250 SBD", it will add that amount for you in the text box below. Then just click submit, and now you have to wait 3 days before it gets out of savings. That's the 3 days you have to wait to get it out.
You seem to have a lot of votes on this post, yet... no one bothered to explain anything. I hope this helps. Peace.
