you apply for rm89 or add on rm10 become rm99?because from what i understand in their ads, rm89 without unlimited calls, pay per use for voip, for charges per minutes not sure how much they charge it. if rm99 will got free unlimited calls and got free dect phone, if i'm not mistaken.

plus you never used any phone calls. they should not charged its
if you charged like that, if i apply for rm99 with unlimited calls could be charged with sst near similar like you.
i think better complaint direct to maxis branches or mcmc for faster updates if still no action from maxis by next week, your problem consider new. i know a bit leceh one, but i have read in here before regarding changing his old package to this latest 30mbps. complaint from call and live chat no action. then he go through maxis branch and mcmc. then the next days he got new plan.

so, you got charged rm15 too?

They should give an options in their application form for customer whether want by paper bill or e-billing email. So, tm much better on paper bill because they charged one time only at first month for new user then next month until user want to terminate they didn't charged for paper bill. They should mention to user that they will charged paper bill on first month or every month. Plus, they charged you additional for voice without you applied for its. So, the agent that you applied should be blame at the first place because not clearly told you what the outcome on next day.
