Videocon d2h Cust ID: 90802853; service malpractice, I'm unable to view the World Cup

I've been a Platinum package subscriber (their highest paid package) for the last 5 years.
My ordeal began on 18 Jun 2018 when I called in their customer care to check why I'm unable to view the World Cup in spite of being a Platinum package subscriber. I was very curtly informed that, I need to pay extra if I want to watch the world cup.
When I tried to explain to them that I'm a premium customer and shouldn't have to pay extra to watch important world events, I was informed that I need to pay if I want to watch the world cup.
Hence, I decided to disconnect my d2h service and called their Customer Care again on 22 Jun 2018. I requested cancellation of my service and refund of the balance available on my account. That's when all hell broke loose...
I was repeatedly told that I don't deserve to watch the world cup as I've not subscribed to the channel. I was told that "I'm raising a hue and cry over nothing", that "I'm not willing to listen to the suggested alternatives, unnecessarily arguing" etc.
Since I'm disconnecting the service, I will also need to pay for the dish antenna, cable, set-top boxes etc. which were issued free 5 years ago when I subscribed for the service
There would be charge of ~ INR 2,000 for disconnection and technician visit which will be deducted from my available balance of INR 10,900/-
These are words which no customer wishes to hear especially from a paid service provider. I made the request again and was informed that the technician from the back-end team will contact me within 24 hours.
I didn't had anyone reach out and on 26 Jun 2018, I had to call them again. I pleaded with them to process the refund as my services were already deactivated and have the technician complete the disconnection service.

I waited till 29 Jun 2018 for any update but there was none. I called the customer care for the 3rd time with the same request and this time spoke to a supervisor (named Yogesh). Not only did he repeat the same rehearsed lines - that a technician will call within 24 hours for disconnection but outright refused to share any alternative channel for registering a compliant. As per his words "I can't tell you when the technician will call but the request is sent to the back-end team" and
"There is no other way to lodge a complaint, you need to write to customercare@d2h.com only"

It's 30 Jun 2018 today, more than 10 days since I contacted them for disconnection and I'm still waiting for a technician to call or visit me....
Meanwhile, they've already disconnected my service since 26 Jun 2018 and are still charging me daily. On 22th Jun my available balance was INR 10,900/- which became INR 10,815/- on 26 Jun 2018 when my services were disconnected and reduced further to INR 10,791/- when I called on 29 Jun 2018 and now when I check today, it's showing as INR 10,767/-

Videocon d2h have been deliberately delaying the disconnection so that I don't get to see the world cup and all the while continuing to charge me for the services which have already been deactivated. This is how they make customers suffer for being loyal to them!!

I've got a few questions and want your guidance and hope you will be able to help with them and take the matter further:
1. When I subscribed to the Platinum package 5 years ago, the package included all available and new HD channels. Over the years Videocon d2h has disabled a great many of them without consent while increasing the package cost each succeeding year. Can a service provider unilaterally unsubscribe paid channels without consent from the customer?
2. Since the Platinum package is the highest paid package they provide to the customers, how can they still charge extra for subscription to a channel for world events like the Football cup?
3. When my services are already deactivated effective 26 Jun 2018, why are they still continuing to charge me?
4. When a customer makes a request, why are they made to run around like fools and told each time that they need to wait for a callback which never comes?
I've been waiting for over 10 days for a simple disconnection request. Not only have they failed to heed my request, they're deliberately delaying the process to ensure that I miss the World Cup entirely. How can I take action?
