Most likely the transaction not posted by 22 Aug, so need to wait for next mth. I assume you bought stuff in july?
ok i got to the bottom of it after calling. The bottom line is
JAPAN AIRLINES website is not recognized as online transaction by Standard Chartered.
anyway these were my transactions:
23/08/2017 30CASHBACK 22.80 CR
20/08/2017 JAPAN AIRLINxxxS'PORE SG 914.00 DR
22/07/2017 30CASHBACK 60.00 CR
19/07/2017 AGODA.COM INTERNET SG 299.54 DR
That was all I spent for the period.
So the latest cashback, $22.80, was for the period of spending from 24 July to 23 August, and actually for the agoda spending on 19 July, because the posting date rolled onto 24 july.
So they told me that the 20 Aug Japan airlines spending was posted on 23 August (still fit into this cycle period) but was not recognized as an online transaction but rather a retail transaction. I explained it was done on their website and after some long waiting eventually they agreed to consider it an online transaction.
So I suggested that they could alert customers of vendors who have this issue so they can inform the vendor or avoid spending on these vendors. They said it is not up to them but rather should fall upon customers to note these problem vendors themselves, and they can call Stanard Charterted to contest the amount when it happens.
I thought it was quite 'pass the problem to other people'.
So we have JAL website not recognized online transactions. Maybe we can start a list so we can refer to all the vendors easily?
