Vodafone India — poor network

Address:

Bellary, Karnataka, 583101

Since 8days poor network in my coverage area by vodafone india, i complained to customer care and vodafone office is well but still there is no reply from them and they not yet sort out my problem this seems how careless they were.
Whenever i used to on the data then network completely vanished and i cannot able to access data. And i recharged 500 rs for 3 months package, but now it seems waste of package.
Please sort it out as early as possible
Thank you.
