POSB's Puzzling Overseas Spend Promotion

Despite voicing the puzzle to POSB Hotline, there has been no clarity to this computation in relation to POSB's 2% rebate for Overseas Spend.

Promotion link:-

In the promo link, it says:-

Get 2% Cash Rebate on your Overseas Spend
Your POSB Everyday Card now lets you enjoy more savings when you travel. Charge to your POSB Everyday Card when you travel and get 2% cash rebate⁵ on your overseas spend!

However, in the T&C, it says:-

Full terms and conditions

5.   Subject to a minimum total spend of S$1,000 on your POSB Everyday Card within the same calendar month and capped at Daily$10 per Card account per month (effective 01 February 2015).

?!?

First off, to qualify for the promo, spending $1,000 is a must.

So happily, you would think that you are getting $20 as rebate based on the promo of 2% on $1,000.

However, according to the T&C, your rebate is capped at $10 (Daily$10 per Card account per month).

So after spending a minimum of $1,000 to qualify for the 2% rebate promo, you can only get a maximum of $10 rebate.

The effective rebate is therefore 1% and not 2%, as claimed in the promo.

The Customer Service Officer agrees with me.
I've asked for a revert confirmation from POSB Marketing in May.

But there has been no clarification till now.
