Punjab National Bank [PNB] — Refund of money is not done

Address:	Muzaffarnagar, Uttar Pradesh, 251001
Website:	[email protected]

I have done a online transaction last of December of 2500rs The rupees got deducted from my bank account but not come in my online transaction wallet. I waited from some days then logged a compliant in pnb on 9 jan. Their executive said to wait for 45 days and the money will be refunded. I taken follow up till 45 days but nothing happened.
After that i marked too many mails to escalation matrix of pnb, but none of them is responding. They are saying that my transaction is successful. How can it be successful if i had nit received the money till now, even i asked for the artifacts if the money has transferred but the people are not responding.
Please help
