Quicker Job — delta infotech -data entry

I saw an add applied for data entry job in quikr. The name of the company is the delta infotech. The work was to convert pdf to excel. I paid rs.369 but haven't received any such pdf files from that company. They are not even responding the calls. They mentioned in the website that they will give the pdf file 15 minutes after the payment. But i didn't get anything even after 3 hours
