There is no particular Cosmic Serum to make a person call back and say sorry.
But there are Cosmic Serums to heal the mental status and relationship of all involved.
You can send LOVE SERUM to this person frequently.
Also write the name of the person , your name and your wife’s name in a circle.
Energise it with CALM DOWN SERUM and ONE SOUL SERUM frequency.
You can give ALL CLEAR SERUM to the situation..
I am sharing with you based on my experiences, when we expect a person to say sorry we are actually in anger and maybe even in ego. Rather why not think like this that our relationships should be healed so that we are happy and peaceful with each other. Sorry will automatically come or may not be required.
