Vodafone Tarang app is a great step from Vodafone India towards improving service and network quality.
Here, user can complain directly to Vodafone administration about their network and service issues.
Their complain will be taken on highest priority and will be resolved into few working days. Once their issue will be resolved, user can check it under resolved issues.
If user will not satisfy, he can mark that as Unsatisfied and that ticket will be again open as new Ticket and Vodafone team will try to resolve it ASAP.
