Compare Dth / Vserve eCommerce Sales & Service — my airtel dth invoice and free voucher and one month offer pack

I have purchase my airtel dth connection through compare dth online services before two days but i have not received my invoice till now. No one is replying about it. When i am calling to thier customer support, executive received my phone. When i am asking about my invoice, offer pack they are disconnecting my phone. It's fraud to customer. They are cheating to customer. No one is responsible person to deal these issue. I requested to google please don't use their platform for cheating customer for suchtype site. I will go in consumer forum for these issue. Please bann these site
