Train cancelled 1 month prior what to do?

I had booked Vande Bharat from Jammu to Delhi yesterday. But got the message that the train has been cancelled the same day evening. What is this?

I have also called on 139 to enquire through automateed system and it says that the ticket is confirmed, nor there is any email sent to me. Moreover the ticket being booked is being shown on the irctc mobile app.
Should i still infer that the train has beeen cancelled or not?

Moreover i also checked the same train ticket availability on the irctc website on the same day and it still shows that the ticket is available.
Please tell what is this nonsense.
