Can I just get a 2 cents from everyone.

I am sort of a light user when it comes to voice calls and SMS, so although I am currently on Maxis Value 50 and my supp Value 30, we always underused the voice call like RM30 for the whole month. However, we are still paying about RM80 per month. Plus I have just added in the Mobile Internet for another RM58, hence feel that it's a bit wasting lar. Any of you have any suggestions?
