When I used Uber to KLIA, I was still using it with AmEx that time. These days I just take cab via CAB2KLIA, all in only around RM 72 for me.

Depends on your location. From my place in PJ, around RM 71.xx plus all the service charges.
I find it cheap, even now Grab has promo for RM 65 from/to anywhere in Klang Valley-KLIA/KLIA2 but it is without toll fees yet.
So, it is about the same. If without promo, the CAB2KLIA app is more worth for me.
Anyway, at least now I can take Grab from KLIA/KLIA2 with the promo rate.
CAB2KLIA is only to airport.

Entitled for cash back.

Only unbilled statement has both transaction and posting date. Statement only shows transaction date, so safe to say it follows transaction date. However, there were a few cases reported here for missed cash rebate due to month end, so need to call and check with CS. Better avoid month end's transactions.

There were few missed cases reported here, so need to call CS and raise a dispute for investigation. In short, avoid doing month end's transactions.

I will not waste my energy to spend it at the end of the month to save my energy arguing with CS.

Yeah, especially I feel that our UOB VOX's transactions can be adjusted and not die-die must be on a specific date. Like pay bills earlier and all.

Every month I will have at least something to spend online, so I don't need to resort to that option, so my monthly charges will be auto-waived. Yes, pump 10 cent can if you really want.

Well, if situation forces, can't help it lo but if can adjust ourselves, then try to do that.

Yes, just use it to pay your bills.

victorywp, please update this if you haven't done so.

Statement will only show transaction date, so most likely based on transaction date.

Don't take my words for granted because UOB's system does have glitches from time to time. So try to avoid doing transactions at the end of the month.

Try asking if can appeal?

Just in case, if you have printed any latest CCRIS? You can also attach that as your supporting.

But he clears all before due date?
