How hard is that?   

I just checked my unbilled transactions for both Aeon Watami and PBB VS, the payment is posted succesfully in Aeon and merchant name shown on PBB VS is "POS MALAYSIA-ONLINE KUALA LUMPUR MY" high chance will get the cb i think 

If i manage to get the cb from PBB VS, i think AEON WATAMI and PBB VS are the best combo cards for insurance premium (from now until Apr 2016) 

1)Aeon Watami 3% combo with PBB VS 6%
Cb effective rate is 6.82% - if you pay 814.40+1.50+2%convenience fee +6%GST = 833.29
Cb amount is 50.00(RM833.29x6%) from VS, 24.43(RM814.40x3%) from watami, then minus triple charge from Posonline 18.89(1.50+16.32+1.07). To calculate the effective rate, (50+24.43-18.89)/814.40 = 6.82%

2)Any Aeon card combo with PBB VS 6% - since Aeon watami benefit discontinued after Apr2016
Cb effective rate is 3.82% - if you pay 814.40+1.50+2%convenience fee +6%GST = 833.29
Cb amount is 50.00(RM833.29x6%) from VS,  then minus triple charge from Posonline 18.89(1.50+16.32+1.07). To calculate the effective rate, (50-18.89)/814.40 = 3.82%

3)If VOX and CimB 5% online cb works also, cb effective rate is 2.83% - if you pay 977.65+1.50+2%convenience fee +6%GST = 1000.00
Cb amount is 50.00(RM1000.00x5%) from UOB/Cimb,  then minus triple charge from Posonline 22.34(1.50+19.58+1.26). To calculate the effective rate, (50-22.34)/977.65 = 2.83%

EDIT: Correct me if my calculation is wrong.
