My due date was in February 2018, and I formally informed my company about my pregnancy on September 7, 2017. They sent me on leave starting from January 22, 2018. I have been inquiring about the maternity policy since September, but they have never responded to my emails. They paid me my salary from February to May, but now, for the month of May, they have not transferred my salary. When I asked HR about it, they informed me that the payment is on hold, both verbally and through email, which they have not replied to. Please advise on what actions I can take.
