Maybank kill switch is for online banking access only. Cards don't have lock or kill switch feature.
Malaysia banks somewhat do things differently. Previously a relative remit some money to me from maybank Malaysian. But Maybank deposited 3 times more than the initial amount. 4 figures become 5 figures
After i saw it, i immediately call Maybank hotline to report it ask them crawl back. But Sg side says its nothing to do with them. Ask me contact Maybank Malaysia. Imagine my relative has to take leave go all the way down to the branch where the money is remitted to report it then they freeze my account and crawl back after days
-_-
After this incident i always have a set of different expectations from foreign banks.
