This is the way I don't like celcom. The rules are always changing in short period.
Last time it used to have reload internet bonus and per minute charging block for voice call but now they revoke the reload Internet bonus and change the voice charging block to 3 minutes with no announcement. What a way to carry out the business.

I think this is not with Celcom alone, but rather most of the major telcos calculate the validity for reloads in a similar method - the validity periods of 2 separate reloads don't stack. So we've to be very careful like when we want to take advantage of a certain promotion, to get a reload voucher for the whole required amount.
Those reload bonus and charging system, if you're referring to the time when Magic SIM was just launched, I believe they're more of a new-launching promotion. They probably decided later that it's "not healthy on their profits"...
As for the lack of announcements for removing such goodies, again I observed most telcos won't announce these "not so good news", and only update their website. To be on the safe side, I normally visit the website or discussion sites to look out for any changes.
