Wish Net Private Limited — Broadband connection never worked

Address:	Kolkata, West Bengal, 700084
Website:	www.wishnet.in

I live in garia sitala mandir area, kolkata 700084,
I have unlimited package of 512 kbps speed, but i forget what unlimited service is,
Wishnet helpline no[protected]
Local service provider number[protected]

Wishnet is constantly cheating on my service, they have no control over their local operators, they dont respond when called (Their toll free number is only accessible by registered number and when they decided not to take calls they just put that number in busy ), neither their local service provider respond.
Constant ping loss, or half of the day connection not available. Sometimes login is also not possible.
I request people not to take this connection.Or wishnet should take necessary action. I am really frustrated with this connection.
