Cars24 Services — Nobody showed up for my appointment and no updates thereafter

I had an appointment for 12 PM today where cars 24 executive was supposed to come for home inspection ( appointment ID - [protected]) but nobody visited. Nobody informed me, nobody called me. I reached customer care thrice, all I got is someone will call you back which never happened. They have no supervisor, They have no local contact where I can reach. They have no escalation matrix. All I had to do was to wait at their mercy
complaint number - 564609
There is still no update on if anyone will come or not.
