hypothetically speaking there is a chance that , the wrong dp id which we entered may belong to some other person... but i believe if the registrar checks the PAN with the DP id , automatically it will be rejected .... but as
@Paymzia sir mentioned , its better to apply one more retail to cancel ...
again if by chance it gets wrongly allotted , it will be painful process to you , to prove that money is urs , account is others ... but always there will be way to get back but that will be painful and time consuming ...
