The only answer I have to you: I learned not to give a damn about trolls. Maybe start something useful with your life instead of claiming things that aren't true?
None of it really has to be untrue to not draw the same conclusions. It’s possible that the phone crashed after some time, it’s possible they deleted messages and gave up because, as the parent comment suggests, they decided not to feed trolls.
Citing sources for specific claims does not mean that the overall conclusion is inherently true.
