Wrong transfer token in Crowdsale contract

Hi everybody:

In a crowdsale contract, it has been deployed with a test token instead of the correct mainnet token. To make matters worse, they have sent a number of mainnet tokens that have been trapped because the interface does not match.

My attempts to solve it have been to inherit the contract in one with the appropriate interface to try to get the tokens.

interface TokenInterface {

    function decimals() external view  returns(uint8);
    function balanceOf(address _address) external view returns(uint256);
    function transfer(address _to, uint256 _value) external returns (bool success);
    function transferFrom(address sender, address recipient, uint256 amount) external returns (bool);

contract Rescate is Ownable { 

  TokenInterface TokenContract; 
  address public token;
  address public addressCrowsale;

            constructor  (address _token, address _addressCrowsale
            )  public {
                            TokenContract = TokenInterface(_token);  
                            token = _token;
                            addressCrowsale = _addressCrowsale;

              function withDraw() public  onlyOwner() {
                uint256 rest = TokenContract.balanceOf(addressCrowsale);
                require(TokenContract.transferFrom(addressCrowsale, owner(), rest));

              function balance() public  onlyOwner() view returns(uint256){
                return TokenContract.balanceOf(addressCrowsale);



But the transfer form is not possible because for this he would have to get the crowdsale contract to allow the transfer since he is the owner of the tokens.

I think it is not possible then to get those tokens. Even so, I create this post just in case there was any possibility that I did not know
