Punjab National Bank [PNB] — Money is not credited

Address:

560100

Flipkart refunded Rs. 1375.00 on 13 th of March, 2016 but the money is not credited in my account till now. My bank is Punjan National Bank, Electronic City branch, Bengaluru. Flipkart has given me th ARN no.: FPNB[protected] and told me to tell about this no.to the bank so that they can track the transaction. But PNB tells me, everytime I call the customer care that they can't do anything with this no. and uses to blame Flipkart. I am trying to call PNB electronic city branch with the given phone number but nobody receives the call. I want PNB to take some steps to credit my money in my account. They can't be so irresponsible and should not provide phone numbers to the customers if our call is not important for them.
