I registered for broadband connection in the month of September, 2016. The engineer came to my house to install the internet cable and broadband. Due to technical reasons they were not able to setup the internet.
Then, I asked for refund of my registration amount on 21st September, 2016.
Since that date, the company has not refunded my amount. I have called them more than 20 times. Everytime they tell me that they would get back to me.
But they do not revert.
The amount which I had paid for registration is 1034 INR. Also, I have submitted cancelled cheque to process the refund amount. But no response from them.
