Reliance Bigtv — stb not received

Dear sir/madam,

I have pre booked reliance big tv on 1st march, 2018 but have not received set top box nor received any update.

Now almost 45 days past, but still waiting for the response.

Kindly do the needful as soon as possible.
I am trying to call customer care but not successful on both numbers given on its website.

I am worried about my pre booked payment now. There should be regular updates, what is happening there.
