YMMV Chase App Offer $40 back when you make TWO $15+ transactions with AT&T wireless

Here is the picture of the offer I found in the chase app. https://imgur.com/a/CLydBm5?desktop=1
The link they provide with the offers details is completely useless unfortunately.

Looks like you can make the 2 purchases over the phone, online, or in store. The dates don’t make sense but this seems like easy money for someone who pays AT&T every month anyways for services.
