ICICI Bank
Fund transfered from HDFC bank to ICICI bank through NEFT Fund Transfer but money not showing in my ICICI bank A/c

Fund can be transferred from one bank to another through NEFT fund transfer. It usually takes around 1 or 2 working days for money to get transfered. This is applicable for any bank except ICICI bank. It takes more than 3 days for the money to get transfered. Why does icici keep the with it for so long. Is there any RBI guidelines in this respect? How can I raise a complain with RBI against ICICI bank?
