NoBroker — not returning money as per money back guarantee tenant plan

Not returning money back as guaranteed by them if they cannot get us a client and if we find from other sources. Their service was very poor to start with and not got any leads through them in spite of giving a hefty fee. Now after repeated requests and submitting supporting documents as asked by them now not even getting any response too from them.
Looks like it is a fraudulent attempt by an inefficient team to make quick money.
This definitely needs investigation.
