Harassment by real estate broker

If you have such promise in written, then you have concrete ground to press charges and even sue the broker, as it will be really tough to prove any verbal assurance.

Secondly, in my opinion, negotiations could be a better way to resolve the matter, where ofcourse you won't get a complete refund but could negotiate some refund, if such a negotiation could be arranged.

However, given the Broker's attitude, it seems really difficult as well. (Although, needlless to say, such broker will be in big trouble if there's no valid registration of such broker under the RERA Act.)

However, the problem stated above seems genuine and you can approach the Regulatory Authority established under the Maharashtra. https://maharera.mahaonline.gov.in/contactus/contactusdata

You are entitled to demand back paid rent for the period when you vacated the property and were not using the same. So far brokerage is concerned, except you have any contrary terms, you are not entitled to brokerage as broker has performed its job.

Thank you for your reply. 

So the contract was not complete so it's not mentioned in a formal document. But I do have a message from her stating that the 'brokerage can be collected on pro-rata basis from the new girl' incase one of us has to move out.
