Another question,
if subscribe to RM10 unlimited Xpax social pack,
if credit validity expire, will Celcom block access to Internet even though haven't use finish internet quota?

If true, who can I complain to since Celcom written 'No time limit' in their ad?

I already quit Celcom. Watch out when you surf in lowyat using mobile. When you accidentally click an ad, you are automatically subscribed to a s**t Celcom service.
