Mental trauma and injustice by gm,hrm of psu bank

I am an employee of a PSU Bank working in Pune for the last 5 years. In 2017 wen I conceived, I requested for my transfer to my native place Kolkata in Oct'17 .My husband also secured a job in Kolkata. I went on for maternity leave leave in Nov'2017.Since I had no one to look after me in Pune, I shifted to Kolkata for my delivery which was due in Dec'17. First transfer list was published by my Bank in July'18 and my name appeared in it.However even after repeated requests to the Pune Zonal Manager and General Manager,HRM Deptt,HO, i was not released from Pune. But my junior colleague was released based on the same list. Since June'18-Oct'18, 4 transfer lists were published by my Bank and my name appeared in all the lists. However I was never released. In the mean time due to arbitrary transfer orders by GM HRM, court case was filed against her by a female officer.She was granted a stay order by Lucknow court.But GM,HRM being adamant cancelled all the transfer lists with the instruction that the employees who have already been released will continue to work in their new place of posting rest will not be released any more.Finally she released a list consisting only the male staff and cancelled transfer of all ladies staff. After explaining my condition to her that I have an infant who is still on breastfeed and based on the transfer lists I had vacated my rented appt in Pune and shifted to Kolkata,she forced me to take unpaid sabbatical leave which also amounts to loss of service days. Since August'18,I have written several request letters and E-mails to GM,ED and also MD but till date none of my requests have been responded.I am in tremdendous mental pressure as I have housing loan,car loan EMIs to pay.Being forcefully unpaid for 6 months has resulted in financial disaster for me besides mental trauma. Please note there is no Women Grievance Redressal cell in my bank and Union has also failed. Where can I apply for solving my problem.
