Vodafone — Bad Service and inability to resolve issue

I had availed of Vodafone post paid network in January end 2015. The customer executive at margao goa showroom had assured me o[censored]ninterrupted network and 3g availability in my location. To my horror I realised there was no 3G network in my residence for Vodafone. I immediately complained at the margao showroom. Since then did not have any resolution and were acting ignorant and I also mailed the consumer care desk online . I also escalated the issue to nodal office and apellete authority id but all in vain. None of the Vodafone departments were able to assist. It's a clear case of having cheated me. Inspite of knowing that I wouldn't get connectivity at my location I was mis sold the plan by Vodafone. Though I never got 3g network I have had to unwillingly pay the data bill for Feb March April and May with the hope that I would get 3G network. Vodafone has cheated me and had not taken any efforts to resolve the issue
