I am facing the same issue..
Initially I was known that need to spend RM 1k for RM300 Lazada voucher..
Then in the middle of applying this CC,
the CS told me that either one time spending is enough for RM300 lazada eligiblity.

Then yesterday I call CS again,
asked whether I am in the list of getting this voucher,
she told me need to spend RM 1k pula within 60 days (the initial promotion)..
(btw, the link from fly is invalid?)

Now..in confusion...

i though jz any amount 1swipe will do....
