The pickup instructions mentioned free shuttle service from all terminals, but this was not the case. While waiting at the designated spot at T4 and calling, I was told a shuttle would come but after waiting 35 minutes and calling again, I was informed that only T2 and T3 had shuttles. After going to T3, I was then directed to T2. It took another 15 minutes after a final call for the shuttle to arrive, with the whole process taking 2 hours!
