Take it to a professional who will Run bolts through the wall and bracket them on the inside.
Someone who doesn't know how to fix the problem is the last person you want fixing the problem.
I would like everyone who gives advice here to consider the tone of the question:
'we can't figure out how to fix the holes'
Is not a prescription for
'fill it and use the same type screws'
Not everyone need be a self doer.
The question often reveals this.
