IDBI Bank — Fraudulent practices for remittance services o[censored]SD via intermediary bank in US

Address:

Kolkata, West Bengal

I am NRI settled in Cambodia. I had transferred USD to IDBI bank in Kolkata via the intermediary Bank CITIBANK, N.A as advised by IDBI. However received money with way lower exchange rate. On checking, it was informed that IDBI received money as NEFT from AXIS Bank. While my remittance slip has clear instructions for transfer to IDBI. My local bank ABA in Cambodia suggests it to be some understanding between IDBI and Axis to fool customers and gain from such fraudulent practice. I stand losing around INR 10000.00 while IDBI has washed its hand's off. Whom to complaint
