Customer keeps calling me freaking out, she can’t afford her payment

I sold a customer a truck last month and before she even made her first payment she tried refinancing it and only lowered the payment by like $75. Now she’s telling me whether she refinances or not she can’t afford it and put all her money down from savings and it was all she had since her husband died. We can’t buy the car back and we can’t get her into anything else because she lived out of the country for 30 years and literally has no credit score or credit history. Trying to figure out a way to help her, everyone at my dealership is telling me to just block her and ignore her calls but she will just come here in person (she’s done it a couple times) she ditched her truck her at the dealership and it’s currently sitting in our parking lot. Anyone got any advice? (I know it’s pretty much her fault she signed on the dotted line and knew her payment and she should’ve known better I’m just trying to find a solution for her)
