me myself just cancelled my public bank cc. but 1st i called up CS on the procedure & was advised to go to any public bank branch.

1st, you need to double confirm wif counter staff if got any outstanding. if yes, pay in full.

2nd, i was asked to see the bank's CS. then, fill in a form, a photocopy of my IC was needed, & surrender my CC. they will cut the CC & attach the CC with the form to confirm the cancellation. and i was also given a photocopy of the cancellation CC form for my reference.

all done in 20 minutes.
