From what I understand, if you apply CC by this year, even you didnt activate, you are liable to pay for the GST, since it will immediately imposed on your first statement. But I think you should call SCB customer service to clarify this matter.

Sometimes when you hold too much credit card, Bank will see it as a commitment of 10k, and they wont give you another 10k credit. The best way before you apply new credit card or loan is you cancel the unused credit card first so it wont appear on CCRIS.

As you mentioned, you got RM38 credit from SCB with your new card. so you actually gain as far the government tax is concerned. Might as well keep it for a year.

As for saving RM50 tax from AMBank and EON Bank, call both banks and see if they willing to absorb the RM50, tell them you are considering to terminate the card if they say got no incentive/program . If both banks willing to absorb the RM50, then you loose nothing. If both do not want to absord the RM50 tax, change to HLB.

I got my letter from SCB today to collect my iPod but to date I never received my SMS.

were you required to pay for the GSt?

Competitions are stiff in LYplaza. Perhaps they squeeze their profit margin to the maximum in order to offer the best price.
Depends on the situation lor. If the price after adding 2% is still cheaper than other shop, then go for it.

I bet most merchants dare not to put an item "credit card surcharge" in the bill because they know they'll get penalty if customers go to complain.

"I am not sure, whether 3% of credit charge, should charge to customer?"
- They shouldn't charge the extra 3% to the customer. In fact they should give the customer 3% discount so as to encourage more customers to use their cc's and therefore gain more business.

"Is it legal?"
- You need to ask a lawyer that since most of us are just laymen when it comes to legal matters.

"If we face this situation again, we should phone to bank to complaint or the shop management?"
- But of course, not only should you phone up the bank to complain, you can also make a report to the consumer's association and if you really hate that retail outlet you can try to cause more problems for them by even making a police report!

But wouldn't it be so much easier if you just pay cash unless you are the very contentious kind of person just all out to cause problems!

How long did you holding your cc?
Mine maybank already use 1 year plus also didn't increase any limit 

Try writing to BNM and complain. Your chance is slim but no harm to try it out.

Have u read the T&C clearly which have such rule to block u cancel the cc within 6 months???
