Vodafone — delay in broadband connection

I applied for broadband connection of you broadband and also paid amount of 4000 for the same the employee (Nisha rajput) who gave me all details about the plan, through which i completed the online transaction assured me that the connection will be available within 2-3 days as i was in real urgency of internet connection, now she is not responding to any of my messages nor calls. I am really fed up of calling customer care numbers that says they will send their engineers but its been more than 5 days now, this is too much i would take some harsh decision if my query is not attended with immediate concern.
