Shine.com — refund from employees

Dear sir/ma'am, yesterday i got a call from an employee of shine.com named nitin chaudhary ([protected]). Who claimed to creditmy refund of rs.90000 on the same day by evening just befor that i have to pay amount of rs.5800 which were interbanking charges. I refused him a lot but he was asking to trust me and send the reciept on his email ([protected]@gmail.com). I did so but now his number is switched off and i did not recieve any refund. I want you to take strict action on such company's employees and also if possible please concieve my refund on my account.
