Videocon Industries — service, wifi not working

What's the point of having a customer care service if you don't content to help us resolve our issue and those customer care (Who we talk with) are horrendous have no knowledge or grasp the aspect of what the customer wants. One time i'd called them asking about why the package price changed and to complain about the previous person whom i had spoken with (The guy was bad mouthing)
Even they transfer my called to their superiors. After having chat with him he said he will register my complaint and will receive confirmation about the complaint. Guess what nothing happened whatsoever. Today i called the customer care to talk about why my wifi cant connect to setup box he told me wait then i waited for about 15 mins. I'm furious
