As Binance have told you multiple times, you are currently being externally investigated for suspected fraudulent activities. Binance have no control over the speed of this investigation. They are also legally not allowed to disclose details of the investigation. This is all outlined in their Terms of Service which you agreed to upon opening your account.
I wonder how a person with more than 1,000
BTC could escalate the issue in such a random way, which leads to more spam, "this will increase the disregard of the question."
Also, if you try to enter this amount for any place there will be investigations, let alone a platform trying to dispel suspicion of money laundering on cryptocurrencies.
you have hired lawyers and taken legal action, so escalating this issue in this forum will not return your money.
Be patient and as long as you are right you will recover your money.
