Videocon D2h - Fraudulent behavior by the company

The below is the content of the email I've sent to customer care * days back and still haven't heard back from them. They are not answering their call centre numbers from my registered mobile number.
Email Content:
Customer ID: *******. We have * active connections on the same customer ID. I'm drafting this email on behalf of my father.
As per recent conversation with your executive on **th April ****, I had asked about the best offer I could get for my * TV connections to which he responded after looking down on the system that It would cost me *** Rs. per month for all the channels to be viewed as per the current pack. I confirmed whether this amount would run channels on all * active TV connections to which he agreed. I specifically asked him about HD channels as well to which he replied to all the channels that are currently running will continue to run for another month after *** Rs. recharge. Later I asked about some offer if I do a recharge of * months to which he responded it would cost me Rs *** and including GST the final cost would be Rs ***. I again confirmed whether doing a recharge of Rs *** would make all my * TV connections work under the existing plan ( Including HD channels) for * months to which he assured me that it would work and I told him I'll do the recharge just now. After doing the recharge of Rs ***, I received a message stating your account is topped up for Rs *** and your expiry date is **/**/**** which is just ** days. I called the customer care again and your executive couldn't help me as your application was down. I called up again the next day on **th April **** and your executive Abhishek answered, to which I explained him the entire scenario as stated above to which he just rudely responded that this offer is not applicable for you. Abhishek was very apathetic towards me on the phone and later hanged up. This is just unacceptable behaviour from customer care service. I have never experienced such bad service from any other company. How come after specifically asking your executive about the best offer and doing the recharge of the same, later the employees refuse it. This is a case of defrauding the customers. I feel cheated. I need a resolution for the same as soon as possible. Also, you can confirm the same by listening to the reordered conversation from the records.
