Videocon Industries — unable to connect to videocon customer care over phone and poor response via email

I have recently relocated to a new house as on 1st of march and have been calling videocon customer care number on[protected] but i am never able to connect to their customer executive. I am not sure if this number even works,. All i get is a beep sound and the call gets disconnected. It has been more than 5 days and the issue is still the same. As i found the customer care number to be useless i emailed customer care email id at [protected]@dishd2h.com and relocation email id [protected]@d2h.com and received an response 2 days later advising the same template but none answered by question. I emailed the nodal officer which i found from videocon portal and never got a response either. I wasn't surprised. With complete frustration i am writing this complaint that videocon has shown a very poor customer care experience overall and i am quite not sure if i will recommend them. I also tried to change my rtn using the sms option to new one and when i key in the words and send to 56677 as instructed in their website i get a response stating this keyword has been expired. I completely lost hope and for a moment and i thought videocon has closed down all their services in india and they are yet to decommission their website. As a consumer i would suggest you guys appoint a head to look over the operations and customer experience. To start with conduct a survey to know where you stand with customer satisfaction.
Thanks.
