Punjab National Bank [PNB] — about not getting the refund

I ve not get the refund of rs 190 till now after 10 days of initiation. Amazon cust. Cr. Said that it will reflect after 5 days but 10 days has passed and it has not shown. They say to file a charge reciept in bank but bank says there is no such process and referl code is useless. And problem is on their side. So giive me my money as soon as possible.
