Indian Railway Catering & Tourism Corporation [IRCTC] — irctc booking account suspended

My IRCTC Account is suspenied saying 17 multiple fraudulent activities have happened in my account, based on what is IRCTC judging that fraudulent activity has happened . All the tickets booked are genuine and follows the guidelines of IRCTC. The logins where done from multiple IP addresses which I am also aware of. Since there is a family marriage all the tickets booked are for personal use only and multiple logins did happen since for booking so many tickets coordination with multiple people are required, hope you would understand.
NO email or an SMS was triggered to me warning me that my account is being fraudulently used no warning message or notifications came from IRCTC via SMS or email on my registered mobile or registered email. Suspending or deactivating an account without notice is fundamentally wrong .
I need this to be escalated to the higher management . Let me know the procedure to escalate this issue to the next level.saying Creating new personal email id's is not an issue at all since it's free of cost and also doesn't incur any recurring cost . But taking a new mobile costs initially and has recurring life long cost. I am using my exisitng mobile number for almost 10 yrs now . I don't have any other number . I have been a IRCTC customer also for almost 10yrs, I am willing to create a new account but how do I register when I don't have another mobile number and I use only one mobile device having a one sim slot.
