Vodafone India — very poor internet connection

Address: RA 36 URVASHI CMPLX, Ambuja, CITY CENTRE, Chandrapur, Maharashtra, 713216

I am vodafone post paid and prepaid customer. I leave in ambuja, city centre, durgapur -713216 (Wb).
Internet connectivity is very poor in my residential area, though from your nearest vodafone ministore distance only 500 meter and from store 2km.
Several times i made verbal complaints, but no outcome. Even today also i complained to vodafone store.
Waiting for your needful action.
Regards
Prithwish hore
