Airtel — I am complaining about airtel broadband

Hi, i had requested for airtel broadband connection and executive from airtel called me and said that its feasible our area (Bapujinagar) and verified the documents and sent me a link to pay the amout for 3 months subscription.
Later i got a message saying that internet connection is not feasible in our area but i have not got any update on refund. And the executive who made to pay the amount is not picking the call.
