[PH] My grandmother is being love scammed and idk what to do about it.

My grandmother has been talking to this guy for quite sometime now, I knew about it bcs I often borrow her phone for school purposes. Now, my GM has a very high pride and whenever we try to talk to her, she shouts even though UNPROVOKED. Now here is the thing, she already send a total of 600k to the person she’s chatting with. All in different accounts. Idk how the law applies to this and I don’t really know what to do. Can someone please help or give an advice?
