Vodafone India — there is no 4g network coverage at my location

There is no 4g network coverege at my location. My mobile number is [protected], west bengal circle. There is a vodafone 2g tower beside of my house. I can't access 4g internet. All the vodafone customers are facing same problem at my location. My location is a market place. I complained customer care and vodafone store many times but vodafone customer care did not take any steps against my problem.
