Reliance Jio — Broadband not installed after taking money

I had raised a new Jio fiber connection on 13th June and they had committed to install the connection within 24 hours. I even received a message stating the installation will complete by 14th June but no response. i have been calling the executive several times but they are giving excuses for the delay. They have stopped picking my calls and my work is getting impacted without broadband.

Date Raised - 13th June
Amount paid - 2500 INR
Order Number - NO0000LW7SSA
