Nobroker — Loss due to NoBroker legal service failure

I have paid for "Complete Buyer Assist Package" service with NoBroker for Rs. 25, 000 on 4-Apr-2023. This package includes two services.
1. Title verification (for Rs.10000)
2. Assists in the sale deed execution (For Rs, 15000)

NoBroker team confirmed that this title verification provided by their lawyers can be used for loan process which would be accepted by the bank.

For the Title verification, I have submitted land documents to NoBroker lawyer on 6-Apr for the flat which I choose to buy. And received legal opinion from lawyer on 11-Apr-23 as the title is clear and can be proceed for property buy.

Based on this confirmation from NoBroker, I gave 3 lack advance to the flat seller and applied to SBI loan to purchase property. But SBI rejected my loan application as title of the property is not clear. SBI said that property trace is not at all clear. Also when spoke with SBI lawyer they personally advised not-to-buy the property as that was high risk to hold the no-trace property.

I have paid 3lacks based on NoBroker confirmation only, still I am unable to get back my money from flat seller. This is a clear failure from NoBroker lawyer on the title verification which lead me to loss of 3 lacks.

I have raised this concern with NoBroker lot of times, but there is no proper response from them. Hence I am raising here. NoBroker simply ignoring my concern which they promised when taking this service.

Also NoBroker calling now multiple times to close this service as this is aged one. Still this service is having second part "Sale Deed execution" which is not yet done by NoBroker.
Though the first part of service failed from NoBroker and cause loss to me - i have asked for refund of second part of service ( Rs 15, 000 ), but no proper response.

As a customer this is cause hassle and money loss due to NoBroker negligence. I can provide required document/evidence on this.
