Vijaya Bank, PayUMoney And Redbus — Refund the amount

Address:

Bangalore, Karnataka

I booked bus seats in May 15, 2015. My bank account is debited with amount of Rs1640/-. Till date, it is not refunded. I enquired in bank, PayUmoney and Redbus also. I'm continuously in contact with bank and PayUmoney. But no good response from them. I have all the e-mail conversation details.
