It is nice to hear the good news from you that your account is now free to withdraw your funds and it seem every other thing is back to normal but did you know what actually happened and their reasons for restricting your account? It is important that you ask them directly on what was the issue so that you can understand it and if the fault is from you then you also know and avoid what it was, maybe if you went against their ToS etc.

Whatever reason they gave to you will be useful to you and the community on their reputation here.

They will not just restrict your account without any reason you don't know.
