Vodafone India — cheating by post paid plans

Address:

Chennai, Tamil Nadu, 600116

I'm fed up of saying this vodafone is a perfect cheating concern who swallowed my money on a postpaid plan.
I was brainwashed by vodafone client by phone call activating a new plan for rs. 1500 &odd said 15gb internet & all calls free. But in my work space is a retail store in my store i can't even use my internet. I made several complaints regarding this issue more than 10times but no use evening 2g isn't working. They said stories like we put external tower but no use i keep on paying monthly bill without fail more than 4months. All waste so i changed my network. I fought that i won't pay the bill amount which i couldn't use. Now they are sending legal mails. Can anyone help me out of this cheating companies.
