Change the "Scamming" Phone Caller (who ask for money) from Bess Sterling to another Sim

Thanks for the reply @QueenMercy ,
Interesting to know about Straud, but I never had a "lovely neck" call from him.

And yes I had deleted her and I did not receive any phone calls since then.
Using MC Command Center mod I cannot find any hidden correlated traits within her.
And it seems the Entrepeneur trait is not correlated at all with the phone calls.

Therefore I am pretty sure it is because the in-game code.
I wonder if anyone can mod it? Or anyone know any modder who have modded the phone call that I can ask
