I have a few questions here.

1) On the Saturday I received my 2 cards, I spent on a dinner costing RM50++ and linking it to Paypal which costs 1 USD. I was alerted by Maybank SMS for both transaction but on Sunday I spent up to RM215 in one transaction and another RM75 but did not receive any SMS notification, is that normal?

2) I was told that my cc billing cycle is on 6th every month, does it mean that I can already pay the bill on 6th itself and before 26th to avoid any interest charges?

3) Is it possible to pay my AMEX card bill with CIMB Clicks? I have searched around and found that Clicks transaction page only allows you to enter 16-digit credit card numbers and AMEX only comes with 15?
