I have booked a flat in Lodha Amara in February (Pre covid situation), also I have paid initial booking amount and registration fees. Due to covid situation I have lost my job and I have informed same thing to Lodha via email and phone still they are not cancelling my booking and not refunding my money I have paid 6 lacs rupees including registration charges. Since last 4 months I have been following up with them but they are not ready to refund.
Since I have lost my job it is difficult to survive, already drain all my savings and this money is badly needed.
