One97 Communications — Wrong money sent chargeback

Address: Gwalior madhya pradesh 474001

I am a paytm business account holder.
My customer sent me 29000 on 13 march to my business account on paytm.
The money was settled in my account on 14march 5:00am by Account of axis bank belonging to One97 communications.
I had to return money back to customer from my business account So I selected the option send back on transaction page, on 14 march 8:00 am hence money was sent back to one97 communications (axis bank account) instead of my customer.
Also the paytm bank was suspended after some days so i havent got any money back in source account
This one97 being a third party between me and customer has laundered my money.
I want my money back
