Hello,
For some mistakes, SSC provides you with an application to be filled out at the time of verification. For some minor mistakes, they accept an affidavit, and for some other mistakes, nothing can be done. You need to contact their regional headquarters for your particular problem. It’s best if you can schedule a visit or you can call them too. I am leaving a link below that contains the contact details of all of their regional headquarters. If you find this helpful, please like this reply. Best wishes!
