Reliance Bigtv — reliance big tv is not providing connection as promised

Address:

700084

I booked for satellite tv connection of "reliance big tv" and paid rs. 500 through bank transfer. But, i am yet to receive the connection. I received a text message immediately after the transfer of rs.500. Since then there has been no communication from the company. I paid the said amount in march 2018. Reliance big tv promised through the text message that the installation will be done between 30 to 45 days.
My booking id is 14509334 and no. Of connection is one.
