    cout << "Please Enter sum you wish to withdraw from account" << endl;
     cin >> withdraw;
            
     if ( withdraw > balance){          
cout << "Value Exceeds Current balance Please enter new amount\n" << endl;
cin >> withdraw;

            } while (withdrawMenu != 3);

Perhaps if you had some sensible indentation, you'd see it:

else if (mainMenu == 3){


  cout << "Please make a selection" << endl
    << "    1) Withdraw from account" << endl
    << "    3) Back to main menu" << endl;
  cin >> withdrawMenu;
        
  if (withdrawMenu == 1){
                   
    cout << "Please Enter sum you wish to withdraw from account" << endl;
    cin >> withdraw;

    if ( withdraw > balance){
      cout << "Value Exceeds Current balance Please enter new amount\n" << endl;
      cin >> withdraw;
      cout << " You Have Withdrawn " << withdraw << " From your Accout" << endl;
      balance = balance - withdraw;
      cout << " Balance is now " << balance << endl;
    } else {
      cout << " You Have Withdrawn " << withdraw << " From your Accout" << endl;
      balance = balance - withdraw;
      cout << " Balance is now " << balance << endl;
    } else if (withdrawMenu != 3) {
      cout << "Invalid entry. Try again" << endl;    
    }
  } while (withdrawMenu != 3);
} else if (mainMenu != 4) {
  cout << "Invalid entry. Try again \n\n";
}
