Independent tv — dth connection not installed since 10 months

I have booked for dth connection online by paying 500/- rupees on 22nd march 2018 with reliance big tv, they promised for installation within 30 to 45 days. But it has been already 10 months still installation is not happening.in mean time the name of the company changed from rbigtv to independent tv, now this new company owned by same old owners says my details are missing in their system & from past 10 months they are passing time saying today & tomorrow. I have all the details like booking i. D[protected] and credit card transaction reference number. The same details are shared with company through mail & call many times, but of no use.
