Wish Net — port blocking in wishnet

Address:

Kolkata, West Bengal, 700036

Have been using wishnet for the past 3 years and for some reason i need to connect to my home computer from outside my network and looks like all the ports are blocked. When i tried to get in touch with wishnet executive they started demanding additional charges for port forwarding. This is completely an unethical practise when i am already paying for my internet connectivity. No other boradband provider like alliance/meghbala has this problem. If this is not resolved, i will be forced to raise this in consumer forum.
