* Effective 1st September 2018, SST of RM25 will be charged for each credit card on a yearly basis.

They should spell out clearly that this will be charged based on card anniversary

Dont worry.
The retention team will call u.

I work at UOB before, that is their process SOP for CC termination.

U call in to terminate, UOB will ask u why terminate, u tell them SST etc, then UOB will block your card and UOB retention team will call u to confirm the cancellation.
