Grahakseva.com — Did not get refund from paytm in my Indian Overseas Bank Account

Address:	Gautam Buddh Nagar, Uttar Pradesh, 110029
Website:	Paytm.com

Dear Sir,
My name is Neeraj and my email id is [protected]@gmail.com with which i'm using my paytm account.
On 22.01.2016 i placed an order, the order ID is [protected] for Rs.4795/- for which i made the payment as follows :-
Out of Wallet - Rs.1439/-
Balance From Bank - Rs. 3356/-
Later on the same day i cancelled the order and the amount of Rs.1439/- is refunded in my wallet immediately and i got the mail that the balance amount of Rs.3356/- is refunded in my bank account and it will reflect in my bank account within 7 days, its been more than 7 days now and i have not received the money in my bank.
I tried contacting on customer care but the response is very poor, i called on their number also but the result is same.
I also asked for transaction ID generated for NEFT but they are not providing that also.
