Need help with pan

I converted my pan card online from minor to major and applied for a physical copy aswell. I went to the bank today to convert my bank account from minor to major aswell. the banker said that she wont convert my account as this pan card wasnt valid and also asked me if i made this illegally and even if this is real.They are asking me to reapply for a new pan card with a signature or to talk to pan card department about this. Can i use this pan to open bank accs and demats account aswell And do i need to sign on this white blank spot or what to do pls help me out guys
