well, from my sat & sun transactions, found that Adonis's posting date is 1 day later - in this case, swipe on sat with posting date on sunday ...
so, supposing if i swipe on sunday instead, perhaps the mentioned merchant will process it the next day, which is monday (1-july), hence may affect the cashback into the following month, july ... anyway, i'm not sure but just guessing based on my transaction record ...
i've mailed to Amex customer service & called Maybank - they assured me as long as transactions are made on weekend (sat or sun), you're entitled to 5% cashback, regardless of the posting date ...
so, i'm curious with the case study of Dell & Agoda above, since the transaction is done on weekend, by right should get 5% cashback regardless ... but then such online transaction may be different

cashback you will get on weekend spend, for sure you will get.. but it will fall in which month, this you need to take care.. you use card on Sunday 30/6, but Maybank still not acknowledged the payment until Merchant processed your payment.. Your time using the card is called TRANSACTION DATE while the time merchant processed your payment is called POSTING DATE.. if you have experience paying Hotel using credit card, you will familiar with this system.. the first time you arrive in Hotel to check in, Hotel will swipe you card for deposit only.. this is TRANSACTION DATE, but Hotel will never processed it.. until you check out, then Hotel will once again swipe your card for full payment and this is also TRANSACTION DATE.. but Hotel will processed your full payment only, during check out which fall under POSTING DATE then only Maybank system will acknowledged it and appear in your statement.. your first swipe during check in for deposit will not be processed by Hotel and not appear in your statement..
You use card on 30/6 but maybe merchant will processed it on 1/7.. Maybank system will collect all your weekend use of the card on 30/6, only if the merchant processed it.. when merchant processed it on 1/7, Maybank system will still capture it as cash rebate, but put it under July spend, since they already processed the June cashback and reimbursed to user.. anyway, this is my assumption based on forumer experience here..
while Dell & Agoda, they are online merchant.. probably their system only collect all your payment details during weekend, and then some human being will double check and approve the transaction AKA swipe your card on weekdays.. if you can see the TRANSACTION DATE fall on weekdays, then you can complaint to Maybank to get your cashback..
