Sobha Developers — cancellation of booking of 2 units[p-7171, p-8112] at sobha arena bangalore not processed since 20, mar 2019

We booked 2 units[p-7171, p-8112] at sobha arena, bangalore in the month of jan, 2019 and due to financial situation we requested cancel the booking of both units before we signed the agreement.
When we approached sobha before signing the booking form, we were respected well and were told they can cancel the booking anytime before signing sale agreement and can refund the amount after deducting processing charges and gst, the response was highly unprofessional and not upto standard when we sent the cancellation request, even after 70 days from request for cancellation, there is no response from sobha team.

We are in great financial difficulties and need the amount refunded badly, kindly assist.

Regards,
Praveen
