Punjab National Bank [PNB] — Refund by amazon not credited into my account

Address:

Rohtas, Bihar, 821115

Sir,
I got similar complaint as above, despite repetitive calls to pnb's customer exe and visiting the branch they are not listening to the grievances, saying that there is nothing as "charge dispute".
Whereas amazon is saying that the amount is sent into my account by 05/05/2017 for rs1049.
