Nobroker — Service Sucks

I have taken a a paid plan from No Broker to sell my house & in 5 weeks only 1 person visited the house. After repeated calls with VInay, Rahul Ravi ( Who claims to be the head of customer service ) instead of addressing my issue they were rude & lifted their hands ...by speaking good english...they are not willing to share their superiors e mail id for a formal escalation and the CEO to whom I sent Linked in messages does not bother to reply...can you tell what is the way forward...
