I was hitting party and nurse popup made me buy a pack I can't keep... With money I need Monday!!!
Please send a help ticket as well as contact your bank and/or app store. And as Kefo said, you can disable the Nurse pop-up settings. I also recommend turning off one-tap purchases in your app store's settings.
As mentioned contact ATA through a help ticket. If you haven't spent those DN's, they may refund but it isn't in their policies that they guarantee it.
