D-Vois Communications — regarding non resolution of internet connection issue

Address:

Mumbai City, Maharashtra, 400022

I have logged several complaints in ion's customer care, sion as internet connection was down on 18 june 2018 but still after 4 days there is no action taken by them to resolve the issue. Every time when i call to their customer care at sion the bpo executive says that they will arrange an engineer for resolution of issue which never happened from past 3 days. I have subscribed for 1 year, 50 mbps plan with d vois communication last monthand need some guidance to take strict action against them due to non support.
