I don't know what to say, but I was an existing card holder when applied. And I got the voucher. So?

Are you by any chance fall under any of the category:

I was 10 months HSBC card holder when the second card applied for Lazada voucher was approved.

not an issue. once you got the voucher, you can decide whether or not to keep it until the annual fee kicks in on the 2nd year.

I wonder if other bank's credit card can be used with the voucher or it has to be HSBC's. It didn't mention in the T&C.

do you recall there were terms from the GemFive vouchers mandating SCB card to be used?

Yes, paying minimum payment per statement is good enough. But remember not to use the card for any other payment, otherwise you will incur finance charges for those transactions.

Must you use HSBC card with the voucher?

That is great news!

It has to be via the hsbc-lazada link.

If you have Word program, insert all the file into Word as 1 file, then save as PDF.

received voucher a few weeks ago already.

I remember getting it within 5 weeks after first swipe.

Yes. it's normal.
But better call to make sure the documents are received. My last experience, although uploaded successfully, the bank claims that it's not received and application canceled due to no response (like it's my fault).

yes, first year is free.

I also received mine within 3 weeks after spent.

by email. so make sure you check your junk box , just in case.
mine came from sender: digital.support.myh@hsbc.com.my with subject: Claim your RM500 Lazada e-Voucher!

in lazada, you can redeem it with any credit card, not necessary HSBC card. So, be street smart, ok?!

anyone who finds out the code can use it.

any card. so if you have other card that gives online cash rebate, use that.

I have tested that use-and-pay-on-the-same-day method, still finance charges incurred.

So, DON'T USE AT ALL.

It was quite some time ago, I can't recall how did the application went thru. Vaguely, there were some legal terms and conditions read out, in a way that you won't realize finance charnges will be imposed for spending during BT period.

No point complaining to BNM, it's our fault for not comprehending fully their legal terms. But I've learned my lesson after being charged and called up CS to inquire.
