i have spent above $1.5k. called in, the CSO (PRC) say will forward to department to check.
... it's the ONLY month i joined the smartsaver and they can't even get their interests right...
It is based on posting date, I am thinking even if some transactions did not post in time you should at least get the interest for $500 spending tier.
Did you have any last minute spending?

I just returned to smartsaver in July.
