Wish Net — bad internet service

Address:

Kolkata, West Bengal, 700028

I am been having bad internet service for the last one month but no one is providing a proper solution... Everytime i call the toll free no they say that they are looking into the matter but i am not getting any solution... I registered more than 20 complaints in the last one month but nothing happened..

Main problems :

Ping loss even at idle..
20 request timeouts at every 1000 replies (2% loss)
This usually happens at the peek hours everyday (8pm to 1am) when the traffic is very high...
