Dear team,

When i'm trying to login irctc with my credential id it gives me an error message "user is disabled"
I reached out irctc customer care they said please drop an email and i did it same, when it comes reply from them its really horrible "multiple fraudulent activities" i didn't understand what is mean that and i reached back to them. Still no response and they told to create new id with new email id and phone no which i don't have alternate.

I'm using this account from past 10 years and there are 7 upcoming tickets which i need to travel or might be required to cancel. Really the way they responded in customer care is really horrible and they don't know even how to speak with customer.
I expect a quick support needed from you.

Thanks & regards,
