Pentagon India — took money as security and would not return my calls

Address:	Thiruvananthapuram, Kerala
Website:	pentagonindia.in

The company's hr named kaabil singhania ([protected]) asked to pay me a sum of 6000 rs. As secrurity to receive the company's laptop and phone.
After having paid this person he stopped replying or sending me the offer letter.
That is when i called him and asked him to cancel my candidature and return my money.
He said it will take him a few days but he did not send me any official mail or receipt and i am scared of all this being a fraud.
I am attaching the screenshots of my payments and the hr's conversation. I also havethe call recordings of the same person.
