Airtel — no 4g connection

Address:

H102, Ajmera Stone Park, Neeladri nagar layout, ec, Bangalore, 560100

Hi
I had bought an airtel dongle with data card number as [protected].
I have been requesting for 4g speed near my house so that i can do my work but airtel couldn't, on speaking to network team they said there is no tower near my house and it will take time.
Before this issue have been going since may at last in july i told them when you cannot give me a proper service i would not pay for it and continued to ask them fix as they were promising to fix at last i gave up and got the connection disconnected.
Now airtel is asking me to pay for 2 moths. Which i have been refusing to pay as they have not given me the basic service requested...
Pls help to resolve.
