My friend is NC with all of her family apart from her Gran (for very good reason although not necessary to go into here, they may have bearing on this situation).
For the last month or so, Gran isn't answering her phone to my friend, just rang out. And now it comes up as 'number not in existence' or 'invalid'.
No obituaries that we can find (Gran would be early 90s) but I am no expert on where to find records.
Friend's Mum is absolutely awful to friend and had succeeded in turning the narrative so that Gran did side with her Mum sometimes over more recent years, but friend and Gran still rang one another regularly. I did suggest perhaps friend's Mum had gone onto Gran's phone and blocked friend but this isn't the case as the number is invalid when I call it too.
Friend wonders if Mum has put Gran in a home.
Is there any way she can trace what has happened that we may not have thought of?
