I have paid oxitel broadband pvt ltd(CIN U72300WB2015PTC206990) Rs 20000.They said they will provide me broadband franchise. Initially they said they will share their isp license, but i have checked that thay don't have isp license.I wanted refund due to this but they denied.I talked to mr sumanta majumdar director of the company.But they are not responsive.Where should I complain?
