After one month + still haven't gotten my return and no status, tried caling their hotline but always forever seem busy.

i think the smart way is NOT to claim full refund.
I used to work out the calculation to make sure i get 100% refund.

Things like OKU claim. If we dont have any OKU children, dont claim.
Or we claim Sakit Critical. I think they may want us to prove all those thing.

I have a fren, dont have OKU children pun claim got OKU children. Cannot la like that
