False offer and advertising

Hi.

I would like to bring to their attention the false advertising as per the uber app promo. It says "50% off all box meals".

I wanted to order 2 of the Zinger box meals, and 3 other box meals for my kids. But there is no discount on checkout.

Why say 50% off all box meals when they do not apply.

I do have a screenshot of the promo offering should there be any dispute of this false offer.
