Hello student

hope you are doing great. As per your query  I would like to tell you that  you need to calm first and chill . Denial of exam due to network ability was completely not your mistake and it is quite obvious you dont have to pay for it and if you have been informed by authorities that you exam will be rescheduled then it is quite obvious that your score will also be considered , so yes you should go for reexam

Hope you found this answer helpful. Good luck for your future
