SCB don't want you to settle their loan
Many years ago I lowered my credit limit for SCB credit card to $2000 after news report of unauthorized transactions. Then there was once I need to pay a one off $3000. Applied to increase my credit limit but was rejected. After that SCB keep calling and sending me SMS to take up personal loan
I got around the credit limit by applying for another SCB credit card (they had the promise of immediate approval and next day courier at that time). The credit limit was increased back to the norm and shared by all SCB cards. So I could use the older card to make payment.
you just need to pay in advanced $1000 to your SCB credit card. Then swipe the $3k.
It’s immediate and no need to call bank.
