Paytm — Failed Payment Amount needs to be refunded

Address:

Bangalore Urban, Karnataka

I had made a online payment(of Rs. 432/-) with Paytm for Airtel Sim no.- 9535xxxx54, using net
banking on 11th March 2014.
When contacted Airtel customer care, they said that transaction was not
successful & the amount cannot be refunded.

Transaction No: IG00SGSKQ2.

But When I contacted my Bank, got to know that transaction was successful-after
verifiying with merchant(i.e. Airtel), so the amount got deducted from my bank
account.

And Airtel Support suggested me to contact the third party website(paytm) from which i have made payment. Please help me through the process.
