Dream11 Fantasy — My account pan verification problem

I am not being able to verify my pan and so I could not add bank details, The message says that pan is already taken, I think it happened because I used another phone number and email id earlier, But I lost my old phone number so when I downloaded dream 11 again I have given another number and also another email id, but I don't remember whether I have verified my pan with the old phone number, So please tell my what to do now I am so eager to participate IPL contests, please help me the earliest
