I have pre booked big tv connection with rs. 499.00 as per the plans given in various media platforms on 12th of march 2018 whose booking id is a12924069.
Which in reply from company says that it will be installed between 30 to 45 day, now 50 plus days are gone there is no response given from reliance.

I have mailed my complaint on reliance customer care email id but they also didn't replied it.

Therefore it is my request to kindly return my booking amount or install the connection asap. Kindly reply.
