Syndicate Bank — refund of money

Address:

New Delhi, Delhi, 110032

Sir,
I had added my money 798rs to my paytm wallet from my syndicate bank account but i was not able to transfer it to my another bank account due to an error. So i refunded my money to the syndicate bank account but the money was not updated to the account and the balance from the paytm wallet has been deducted. It is about almost more than 6days. I had refunded the money on 28th may 2018 and know its 4th june still the money is not updated to my bank account. I had also called the costmer care of both paytm and syndicate bank but both of them are not clarifing thier mistake and blaming each other. Sir do somthing in this matter. Plz
