That's why, it's not that we don't wanna file a complaint, it's scenarios like this that leaves us with no choice but to dig our wallet.
Boost payment system is 24/7, there's no such thing as "system down" unless Boost says so.

Most likely they just accepted Boost recently but haven't got everything prepared yet.

Just now, I received a notification from Boost saying "Thank you for paying with Boost" and being rewarded with a Shake Reward.

The Shake Reward I got is RM 10.

I'm not sure where this reward came from?

Strange that I didn't receive the receipt in my email inbox.
Just paid few minutes ago.

Actually I totally forget this promotion.
And when i checked back my spending last week, only 3 transactions with total spend RM 20.80..
So, just spend as usual
Yup, suddenly received notification from Boost regarding boost rewards then quickly log in to shake it.

Paid Celcom bill for someone...

RM 69.30 = RM 3 shake

Under Bills & Payment, I saw Celcom (Postpaid) in Phone & Mobile
