Address:

vijayanagar bangalore, 560040

My amount debited twice through phone pay and google pay on december 30 2019. I raised the complaint on same day and i have sent my passbook transaction details proof to show them. They took many days and finally telling that we have recived amount only once. Please solve my query. With all the proofs also myntra cheated me. I raised complaint 25 days before they dragged till now and i keep on calling and messaging, they just tell me to wait and my issue didnt sorted out yet. Please help me to get my amount back (1338/-).
