Dude, I feel your pain. I recently switched to postpaid from prepaid and just 2 days ago my line got barred for the 2nd time in 2 months. First time I went to their center, and they said SIM card prob. I changed sim card and it was ok after 2 hours. Then 2 days ago I suddenly got barred again! Can't be outstanding also, I just paid 2 weeks ago and both my sis lines are still usable (family plan). I just lost all hope in Maxis, haish.
