Yes, it is calendar month and will be posted by following end month.
You just calculate back your Dec spending and do a reconciliation. Else, post here and we help you.

Looks like the Amway is the winner here for your RM 50 cash back.
If add other transactions, can only get RM 23.72 cash back. Transactions below RM 50 are not entitled.

Too bad cannot validate if U Mobile payment is entitled or not.

The cash rebate RM 0.80 is from 0.3% cash rebate, don't ask me how is that calculated because I'm too lazy to calculate mine too. I just know all of the transactions I made will be entitled for 0.3% cash rebate as well (on top of the 5%).

Good job. Now we have another two inputs.
How did you pay for the TNB and TM? UOBPayOnline? Then, you can try again this month or something, I'm quite sure they are entitled.

victorywp, another two stuff into VOX basket - Amway Online and U Mobile payment via its website.

Also a minor correction for earlier updated Time Fibre, please add it via UOBPayOnline.

Thanks!
