I did not receive any points for bigpay spending for my flight tickets though

dont think any is available if you need official receipt.

btw, what kind of "official receipt" format you need?

pay thru bank's internet banking/fpx/jompay acceptable? cuz these doesnt provide full tax invoice. just simplified receipt.

receipts from wallet apps?

SYABAS bill payment is available in kiplepay app.

fyi below. i just topup kiplepay using bigpay, and paid PAIP water bill:

so-called "receipt" and transaction history, not sure if this is acceptable by your company:

app-only. no export-able document.

yawor, you reminded me the email part 

Kiple? Never heard before.

my advise is don't use Kiple, as of now, already almost 2 month still didn't see my RM200 went into my bank...
their max is only RM200...

I got a few timeouts,  1 failed after enter tac....... have to follow up with bp

I need 2 more transactions,  maybe do later.

Direct pay to mytnb cannot me?

try mytnb app. it allows custom amount.

the app is linked to your email account, you will receive an email for payment.

While overseas, I can get other card's SMS but not Bigpay's. Don't know what is the problem
