I just spoke to Celcom 1111, as far as I understood from the explanation, Celcom system is pretty stupid.

1. 1+5 free minutes cannot be deducted automatically. That means, if I spoke with my sub line, it is considered as normal rates untill the bill comes in (that's when the system will check how much I have to really pay).

2. Credit limit is not as effective as I thought. One of my sub line used up to RM 700 even though I've set its credit limit to RM 100 and the sub also didn't use RM 700 in one day, it's almost 6 days, then barulah the system bar the number.

Conclusion: I need to monitor my minutes manually. Damn. I'm thinking Digi or Maxis right now, as long as any of them can update the bill faster than Celcom
