OCBC 360 and UOB One have have changed their interest rates, and the requirement to meet maximum interest for quite a number of time since I've signed up on them. Honestly, I have lost track of what's required of me until recently. I got charged an annual fee for OCBC  Plus! Visa credit card recently. Like everyone, I immediately  tried to apply for waiver. I tried online and was  immediately rejected, so I tried via phone and was rejected as well. The automated call also advise me that it will not be reviewed. So... I called up the bank to ask why. And I did. And I realize why... I didn't meet the annual minimum spend. Turns out, I need to spend $2500 per year for the annual fee to be waived.  So I requested to cancel the card, and the annual fee will not be charged if I cancel. Of course I cancelled it. And, I have no more credit card with OCBC....
