You Broadband India — no proper response

Address:

Hyderabad, Andhra Pradesh, 500085

Hi
I Have take broadband plan of INR1947/- from "YOU Broadband" . As per them it will be 3 months with 75mbps with Wifi router free.
If we are not taking the Wifi router, they told i will be getting 1 month extra internet. So i opted for 1 month extra plan without Router

But after end of the 3 months they did not add 1 month and the customer care people are not responding properly and not addressing this.
Its been 10days am keep on calling them for resuming the service for one month, but not responding

Here is my account details:
Account Number: 1734338

So i request you to take a action on these irresponsible people

Thank You,
Naveen
