Clause 4 is Your Responsibility

https://www.myboost.com.my/terms-conditions/

Which sub-clause then?
It'll be auto reversed almost instantly!
Don't be ignorant about pre-authorization charge.

Maybe under 4.2 (t)?
(t) manipulate or exploit our promotional campaigns/ activities or other Services in anyway which Boost may deem as improper, irregular o dishonest;

Did you exploit anything? 

can u share with us a bit, what kind of exploitation u did ?
after your boost acc was barred, did boost return all your balance to u ?

nothing to do with amex
better share your story with forummers here
i guest u must be having multiple accounts for withdrawal purpose

alright then...u deserve to be banned
i think the topup problem happens to bigpay cards n those registering the same credit card for more than one boost acc, n probably also to those accounts with unsual frequent withdrawal activities

one person can have more than 1 account? Boost wont suspend?

Yes, there is nothing wrong. But customers do manipulate their payment behavior to get shake rewards some even abuse till account/card got block, its all about greediness/ethic/moral. Why when paying RM100 bill m2u or going to pos office you don't split the bill to 10 times RM10 each? Again its all about shake rewards.

Be it pay RM100 get shake 10cent or pay RM5 get 50cent, shake reward is just the additional bonus. Back to the point, they provide us the service, we use it, they set rule. Not happy just leave it. Nobody force you to use the service after all.

I believe the clause (t) i posted earlier has something to do with payment behavior like this, where users get blocked eventually.

This can only be answered by boost who set the rules.

But by logically thinking as user la, when we split bills in boost its for shake rewards la...known. Just ask a question, why when you go pos office pay bills(e.g only la when no online banking), you never do like pay RM10 each and visit the place 10 times? The answer is simple. The more we twisting things, the more rules set by boost becomes illogically and pissing you off.

If you have the right mind set...yes, sure you will be happy to get the reward even paying RM1000 and just getting RM1 right? But many people out there not thinking the same. I pay RM10 I get RM1 reward, I pay RM100 I get RM1 reward, why the hell I wana pay RM100....pay RM10 x 10 times ma...            This cause account to be flagged and boom.

same here, whole day cannot access mission page since 10am

AND, no sign on the 30% cb from the Online Boost Day .....

Which mission,  the 30% cb from the Online Boost Day ?

If people got 2 shake,

one RM20 one unknown, means he already won RM20 and one shake that might be RM80 or other bigger price.

And boost if not a platform for you to earn money. Its rewarding you from spending money, please don't get it wrong.

It sounds like to me.
Thats the part I do not want to discuss to make the rewards last longer.     

Some people only entered few hundreds of tokens but expected a guaranteed shake prize 😁

Seems like everyone eligible for this consolation prize! 😀

hahahaha CC is convenient but you still need to pay CC bills with cash tho 

Keep it or donate...can we have a third option "throw away"? 

Seems like hard to get RM 1 shake reward nowadays...

Oldtown - RM 7.60 (RM 0.20 shake)
TCRS - RM 19.80 (RM 0.50 shake)
Nene Chicken - RM 12.60 (RM 0.20 shake)
