Sir
Last two months my net is not connected and same bill amount coming.. Many times i was complaining but they are not responding. I don't know how can i resolve my problem. Technicians coming repairing after one hour it will lost.. They are saying cable problem but my neighbors getting the connection and they are using everyday. For ielts exam i took this modem connection. But i can't use properly for connection problems. My exchange irumpanangadu. They are not taking the telephone also. I don't know what they are doing. Pls give a good feedback.
Thank you
