Shoba properties - Residential plot booking cancellation refund fraud

I booked the residential plot from Shoba Properties (Mysore) in Nov'** & collected the property documents for legal verification by paying booking amount of Rs.*****

The Company has no website or official email id & below their contact details
Address: ***, *st main, surya bakery road, railway layout, Vijayanagar *nd stage, Mysuru, Karnataka ******
Owner Name : Premnath Yadgirkar
Mobile no : ****** *****
email : Premnath***@gmail.com

Plot was booked in Nov'** & the property owner failed to provide one final legal document e-Khata required by my legal consultant to approve.
The Property owner took almost * months to get that document & now due to Covid-** situation am forced to cancel the plot booking considering the circumstances fearing of losing the job & savings due to commitments. I do not want to risk my family which is more important than investing on plot at this moment.

Shoba properties insisted me to accept the refund Rs. ***** on booking amount of Rs.*****/-
I'm against his decision & he's blaming me with illogical reasons & saying that he lost the customers all these days since I did not buy the plot, he has incurred expenses for my site visit & conveyance to get the e-khata from the sub-registration office. This is unfair & purely cheating.
Pls advice
