How to use token number for icitss training

Guys actually i cancelled my icitss itt training course registration for some unavoidable reason. But i made a complete payment and i have this token number which i got after cancellation. It says i could use that token number to apply again gor registeration. But actually i dont know how to use that token number for registeration. I am worried about my money as i made a complete payment out of my own earnings and savings. What's the way to register again without payment using that token.
