Do anyone have any related experience for the same situation? I want to switch my postpaid plan and now Maxis tell me that I have outstanding payment for an supplementary line that is cancelled 5 years ago. Before we cancel the account successfully, we already paid for all the outstanding balance at the same day where we transfer the supplementary line to become own individual principal line. Everything goes well and just really recent only the Maxis suddenly shows notification that we have outstanding balance for the cancelled account which is impossible as we very sure we paid for it. We dont have any transaction record or any bill cause we paid by cash at the Maxis centre.

Can anyone who have similar experience provided some advice how to deal with this except paying for this? We have check with the Maxis centre, they insisted us to pay for it although they couldnt find the record of the outstanding except referring to the system notification that shows the outstanding. They even told us nothing we can do except paying, we can just let it be without paying but the principal line holder will be blacklisted and couldnt do any changes to the plan or subscribe anything.

UPDATE: Thanks for the info but im pretty sure we didnt receive any outstanding bill from the cancelled account at all. Plus, the bill shall linked to the principal line too, so if im paying monthly for the principal line, i shall notice it when i check my bill statement monthly. BTW, i lodge a report to MCMC (advice from someone) about this. And Maxis finally called to inform us that they have remove the outstanding thingy and when ask for reason etc, they say they just remove it and ask me not to worry about it anymore, thats all. I guess the fault is not on me??
