Vodafone India — vodafone only give bills but no services even after repeated complaints

I have made several complaints about network and services but Vodafone is only sending me bills to pay but don’t check it’s own back. No one in Vodafone is serious about complaints even regional manager and they don’t escalate the problem to resolve customer problems. I am facing network problem from 1 year and still same even getting worse my sim shown no service. It’s better Vodafone should close its network in India permanently since they don’t have intentions to provide service and they are charging people to steal their money.
