Ganga and Anandi have not interacted that much but Ganga knows one thing that whenever she is in a problem she can surely fall back to Anandi and that's what she did
Coming to Ganga asking Gehna or anyone else do you think Gehna would believe her and support her when right now the full family is blinded by Shyamlal bhai's goodness. No! They would only tell Ganga that she has some misunderstanding like Jagya told her!
And why shouldn't she call Anandi l? Jagya and Anandi have spent a lot of time with each other more than Ganga has and thats why somewhere Anandi still knows Jagya better.
Ganga was left with no other choice
No offence to anyone but this is what I think 😊
