Not rewarded in store bonus points offer on Dyson Airwrap, because I redeemed points and the total spent was under $799.99

Hi,

I'm hoping someone might have insight on how I can get a resolution for my problem.

During the double redemption event on Oct 1, I purchased a Dyson airwrap which had a 100k bonus points offer in store and online.

I redeemed 400k points for $799.99. I wasn't given points so I submitted an inquiry about the missing points. The response received is that I needed to spend 799.99 before taxes, but I didn't qualify because I redeemed points.

This doesn't make any sense to me as the only requirement on the offer was to purchase the airwrap and there were no additional terms on the store or online offer. There's also nothing in relation to this on their terms that I can find. I've gotten the same response from 3 separate inquiries, and I'm getting frustrated I'm not getting anywhere especially knowing there were many people who were able to get this offer during the same event.

Edit:

Receipt i saw from someone who got the bonus: Receipt
