It's one of those ploys to earn more bucks.

Think of this:

1. Consumer protection is nonexistent in the Philippines; large corporations can do whatever they want, and they have an army of lawyers at their disposal.

2. They come up with that P50 promo, entice you to join, when you join its not working pala.

3. They are counting that some people will not bother anymore to complain because of number 1. Or they are thinking some people will overlook this, since they use their cellphones a lot. They are making money this way. Tons of it.

4. If you do complain, they'll just say they'll rebate you the P50, while CHARGING all the usage.

5. If you complain some more, they might reverse everything, or they'll give you the B.S. of 'did you read the fine print' etc. etc.
