Vodafone India — data & network issue

Address:

Mumbai City, Maharashtra, 400020

I am vodafone postpaid user from past 3 months. I have regular issues regarding call drops & data issues. I had told in december 17 that some upgradation work is going on till 31st dec 17 so there would be issues till then but after many complaints also till mar-18 a single problem is not solved & every time after waiting several minutes & several calls when i was able to talk to customer care representative he was always try to fool me or misguide me by talking anything. I am paying almost 350 a month till i am not getting proper calling & data service as i am able to use only 3-4 gb data only against available 21 gb 4g data. Though it's 4g i am not getting even 2g service & now they want me roam around city for every thing to visit their store and not registering my complaints anymore. Plz help me through this issue.
