definitely prematurely published or need fine-tuning/reword or cancel altogether

Activated my Visa on 1-MAR-2021 so it's the latter.
Will do. The CS wasn't being very friendly either even though it's a chat. She kept pestering me on how I activated my Visa. I told her it's not possible to remember since it's been a year & she kept repeating the question. I asked her how does it relate to my Visa since it's my MC that was suddenly charged with SST & magically activated a day ago. She told me she's trying to link the MC issue with Visa but it still didn't make any sense to me.

No, got technical error (but effect is same).

You took 15000 for 6 months, meaning your statement will show 2500 per month in repayment for this. Your statement will not show 15000 outstanding.

But the effect is correct, since your statement 'starts' at 2500, you spend 2667 total statement amount will be over 5k (even after you get cashback and everything).

Affin fraud team called few days ago said it obviously fraud no need to pay
Will reverse the transaction and send me replacement card without fees
My case is not an isolated case for this website

it is per card activation, no such thing as 1 activation for both cards le

also, unactivated card, nobody will know what will happen to it in the future....

some potential actions:

1) affin may activate mastercard -- sst charged
2) affin may terminate both cards
3) affin may suspend your visa card until you activate mastercard
4) etc etc
