Urban Company — Severe complaint/AC Damage During Service

Address:

603 deepali building 92 Nehru place-110019

This is the first we had hired Urban clap for their service. During the the visit, the person spoilt the ac by removing the gas. During their second visit they again didn't do any justice to ac and now the AC has stopped working. Now in this terrible heat our ac is not working and it's very difficult to work with such high temperatures and no air conditioning.
We had submitted a complaint regarding this day (2nd May) before yesterday and still no one has come to fix the issue, today is the 4th May already.
Please advise how should we issue a complaint? Should we go to the consumer court or put it on social media?

Waiting for your urgent response.
