Indian Railway Catering & Tourism Corporation [IRCTC] — My irctc account is suspended for no reason

My irctc account is suspended and it is showing that due to fraudulent transaction but I have used that account once to book the ticket on 2022 Oct and due to emergency I cancelled it then my account is blocked. I contacted the railway customer care through email and phone and their response was also like that their customer service is very poor and not explaining the correct details and solutions for it. It is very difficult to book train tickets at emergency due to these types of problems. How these fraudulent transactions done in my account because I was not aware that. These types of inconvenience should be avoided by Indian railway
