ok, I just dig out my letter. Under the fine print at bottom of page, tnc, it is stated as follows:
"The cashback earned is based on the posting date of your transactions. Please note that the above revisions will only apply to your transactions posted to your account from 1 July 2015."
So u shld have a case to claim back the max 6% rebate for groceries posted in June provided it hits min spend of $500 in June or $600 for statement cycle, eh this min spend thing is tricky, where are u in this?
I dun have problem as I hold back until July 1, hahaha
For me, I spent above $800 in June. There was 1 posted transaction in July, but even with that deducted my spending is still above $600 (over the minimum $500 or $600 needed to kick in the 6% rebate for grocery spending).
