Vodafone India — persistent network issue and no resolution

Address: E8, DDA BHIMNAGRI APPTS, BLOCK C3, S.D.A., BESIDE SAINT PAUL SCHOOL, New Delhi, Delhi, 110016

Hi, I am from SDA locality in New Delhi and for past year have been facing acute problem of network with Vodafone. Inspite of several complaints to customer care and their appelate authority till date there is no solution and things remain as it is. They just call and say, we have optimized the network and it should be OK. but in reality no change in situation.
Cant imagine inspite of having full network bars neither can one make outgoing or receive incoming calls and Data, once should forget about it.
even after several request for physical visit of technician at the location, no one has visited so far.
Can I get justice/ respite from this harrassment.
