Awww, maxis is shit. Ported out after my data plan incident last time, when they charged me rm800++ for data plan in one month even though i've subscribed to data plan. Complain to ttdi maxis, they said nothing they can do since I deleted sms confirmation and refuse to entertain me, asking me to call customer service. Deal with cs, same shit.
Finally manage to get the issue resolved after i complain and curse them in fb, whereby someone from maxis called and take action.
