Vodafone India — network complaint

I'm Safwan here, this concern is regarding my vodafone post paid number [protected]. I'm facing the network issue from last six months onwards. I have given complain more than 20times nobody is there to resolve my problem, here banglore no one has initiative to rectify this concern, they are spoiling Vodafone Goodwill. Very pathatic service!!! If They couldn't solve a small concern i didn't understand how they going to solve mager complaints??!! They don't have interest to solve customer complaints. I think they don't bother about customer satisfaction.. I'm least unsatisfied now. I kindly requesting you to do the needful. Thank you
