Consumer Redressal

i have enrolled for a airtel broadband connection on 28th may 2013 by paying 4200 rs. to the airtel broadband servicemen. He said that the connection will be installed in 3-4 days. After a week, i called the airtel office to get the status of my installation . in reply they said the connection will not be possible in your region so the amount will be refunded. Now, a month has gone passed and till now i haven\'t got my money back from airtel inspite of calling them repeatedly. Thay gave the firm words that money will be refunded max. by 26th of june but the date has already got passed. my ireciept number is TBLR 645546.
