Vodafone India — network issue

Have been consistently requesting vodafone to look into the matter of the network issue in my area. It has been more than 3 years now that i have sent out emails, spoken to the customer care and recently visited the gallery in currey road, yet, nothing has been resolved. Every time fake assurance is provided but the network issue isn't resolved. Missing out on the important contacts and it's not convenient to keep stepping out and finding a proper network place to have a disruption-free conversation. Kindly check into the matter if possible.
