When someone's been scammed, it's very hard for them to admit they have, because it makes you feel like a rube. You want to create a safe environment where they feel like they still have support and aren't ridiculed for making their mistakes, with the focus being on solutions. You may need to present evidence and give her ways to tell that this is in fact not Elon, because she currently does not have the tools to recognize a situation where she is being scammed. Methods might include explaining that the situation of "a media famous billionaire is personally interacting with her" is too good to be true, especially without extremely good evidence that it's true which she has not received, that intuitively, someone with a net worth of 181 billion dollars would not be asking her for 5k, and that the site she was using just got closed down for scamming its customers out of their money. Use any rhetorical tools in your argument toolbox to give her the intuition that she's been had, how she was had, and explain that these kind of scams happen thousands of times a day and explicitly target the elderly, so she's not to blame for what happened. Once you're on the same page, help cut the scammer out. Block their email, block their social media, block their phone number, virus scan her computer and add an ongoing scanner on her machine, update her phone, install an ad-blocker on her browser, and if you have the savvy to do it, go into her router and block that scam site at the DNS level so she can't get back.
