Address:

EON IT Park, Cluster D, Kharadi Pune, Pune, Maharashtra, 411023

Some people have done fraud with me on 6th of may 2019.
I have paid rs. 84000/- through jd pay to get back initial amount of 4000/-
I have registered a complaint at cyber crime branch pune but they required the bank account number to which i have transferred the money.
There is no one from jd pay who is replying on my concerns.
Please provide me email id of head of jd pay in india or mumbai.
