As per Our Discussion in Comments

Your Given Code is Fine !

Q1. Why its Not Finishing All the Activities ?

Ans. I think All Activities Are Finished Except Activities who have Thread or AysncTask running in Background or not Finished yet!

Q2. How Can i Finish Them ?

Ans. Make Sure your Thread Should be Finished ! or You can Try Timeout etc !

Additional

Pass String with Your Intent 

for this Add Code

intent.putExtra("finishingallact", "yes");

Inside First Activity (Which is not to be Finished)

Try by Making Object of Remaining Activities to Finish Them !

So Try code :

if(getIntent().getStringExtra("finishingallact")!=null)
{
 if(getIntent().getStringExtra("finishingallact").toLowerCase().equals("yes"))
  {
    yourRemainingAct act1=new yourRemainingAct();
    act1.finish();
    // Try Same For ALl Remaining Activities 
  }
}

Answer 2

Try this it works fine with me

// clear whole activity stack

    Intent intent = new Intent("clearStackActivity");
    intent.setType("text/plain");
    sendBroadcast(intent);

// start your new activity
Intent intent = new Intent(OrderComplete.this,
                    MainActivity.class);
startActivity(intent);

UPDATE

sorry I forget to give these lines. Put these line in onCreate() method of all Activities or if you have any base activity you can put it there , then no need to put in all activities.

private KillReceiver clearActivityStack;
clearActivityStack = new KillReceiver();
        registerReceiver(clearActivityStack, IntentFilter.create("clearStackActivity", "text/plain"));

UPDATE

So sorry forget one more thing to give put this class in your Base activity

private final class KillReceiver extends BroadcastReceiver {
        @Override
        public void onReceive(Context context, Intent intent) {
            finish();
        }
    }

Answer 3

To remove all the Activities while opening new one, then do the following

  Intent intent = new Intent(getApplicationContext(), NewAcivity.class);
  intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
  intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
  startActivity(intent);
