Same as mine, I cancelled on Saturday, one of the staffs called on Monday to persuade me to retain the card.
She also offered me 5000 points and I asked her what's the purpose with these points, I can't do much also. Then she said I had more than 8000 points, so plus these free points, I can offset my GST for another year.
I told her, no thanks... I don't wish to keep this card anymore. So, in the end I redeemed a Franklin Covey's ballpen.

Guys, I have a question. I want to cancel my ambank cc. according to this thread I need to call the ambank customer service. There's a few number that I have called 03-20546688, 1300 80 8888, 03-2178888 but the problem is the operators are engaged everytime and have to wait. At 1 time I have to wait even 30 min before running of my patience and hung up.

I have also walk to the nearest ambank branch but the staf just give the customer service no. Do you guys know other way to cancel the cc. Its getting annoying....

shoot an email to the CEO and make them aware
