Girl thought her God is a Genie, like come on you think God will answer your prayer when you invest the money that supposedly for the poor.
It's crazy that Diana doesn't understand that her God helped her because she was praying for the betterment of those around her. The second those requests became selfish her prayers went unheard. Its like her ego was so damn massive she can't put the two together. It's the same reason why Hestia's prayers were answered even tho she hates God. It wasn't about the person it's about the intentions.
There's no way she's that petty to burned his custome right?
