Pacl India — pacl india - unable to register for pacl refund.

I'm writing this on behalf of my mother (Sreemathy e-u[protected] who was an investor of pacl. We have seen the public notice through sebi website that sebi is accepting the refund/claim applications from the investors of pacl ltd. When we tried to register for the refund through the portal http://sebipaclrefund.co.in/, it is showing an error that is -"user already registered". When tried to reset the password via forget password it is showing an error as "invialid mobile number"

We have the pacl registration certificate (Pacl bond) and the bills received for the installments paid with us.
