I have to admit that the card centre is doing a lousy job these days. Too bad that all card related stuff is not a branch level operation. So, whatever you do/request at the branch, they can only forward it to the card centre in KL.
Did you click the "View all accounts" button? If not, you will only see your primary savings account. And if you're still using an ATM card, I will suggest you to change it to debit card because sooner or later, you will need to change it.

Dear Bro, your nightmare has just begun. You will get into more trouble throughout your usage of the card, and even worst when cancellation of the card.

I held few cards of several banks inclusive HLB Mastercard (with a Touch n go Zing card). Mid of 2011, I received a letter from HLB which asked me to update my data within a period, otherwise they will reduce my credit limit because their record showed that I could only hold not more than 2 cards.

My HLB card expired on April 2012 and I wished to cancel it before the expiry date to avoid the GST. Therefore I planned to cancel the Zing Card on October 2011 and the Mastercard around January or February 2012.....

The progress of the cancellations are as below:-

To cancel the Zing Card: I have called the customer service (03-76268899) for not less than 8 times, visited HLB Subang Jaya SS19 Branch for 6 times, visited Touch n Go Office at Taman Desa once.... and cancellation could only be done on March 2012 (it took 6 MONTHS).

To cancel the Mastercard: I have submitted a cancellation letter + destroyed card + filled up a cancellation form in HLB Taipan Branch on April 2012, called the customer service for not less than 6 times, visited HLB Taipan Branch twice, written in a complain thru their website once, and until TODAY (3 July 2012) this matter is still yet to be settled...

What is their conspiracy?

i think a straight forward way is to head to the bank itself and ask assistance from the bank offier.
