@TheEvilMan

Not to get anyone agitated but I read your previous replies and your statement was rather confusing as well. Here's it is in full view - no change from the original post.

"it's replaced because eventually u still have to do replacement, which probably end of this month when HLBB totally took over, and all Eon Bank Account number will change from 13 digits to 11 too to fit their system. The credit card from HLBB is clearly a replacement because after it's activated the old card details and left over debt are all transferred over to the new system."

You have a rather aggressive reply to everyone here thus you invoked a aggressive response to your post as well. That's a fact. (Aggressive replies are my specialty ... ask anyone here and they'll agree) As mentioned, yours is rather a funny situation, so you need to check it out in depth with the bank. We are in no position to advise you with pinpoint precision as to do so ... we need to see your cc account statement over the last 3-6 months and any letters which supposed your card replacement. (I am not kaypoh but the B&W info is an indisputable evidence to help us) Otherwise there're probable gaps which we couldn't see thus will only offend you again if we can't help you with the correct solution.

Plenty of senior contributors here thus I believe they know what they are talking about. 
There are also EON card holders in here as well and they are puzzled with what you are saying - they did mentioned no problem on their side which is likely (though it was answered in a no hold barred manner). Of course you have a problem and the answer did not help you.

If you were to contact BNM, they'll ask you for all the evidences that I mentioned because the evidence will speak for itself.
Again ... if you are not happy with my answer, you are free to criticize or report me. I did not solve your problem but hopefully my comments will help you find the right way/solution.
