I have booked i10nios from first weak November 2020 by depositing rs.10000/-. After that I have done full payment in January 2021. Till now I have not got my car and as I have done loan from bank they are demanding car details or else they can take legal steps as it is almost 2 month from loan disbursement. Kindly take my matter and guide what to do now.
