CDI Number reference

My loan was approved, but later it was cancelled because we could not get the CDI number reference. The school tried to help me get it from the bank, but we could not find it.

The school has a public account and is a registered institution. I would like to ask if there is another way to save the school as a recipient on your system without needing the CDI number reference?

Please let me know if there is something else we can do, or if the school can send other documents instead of the CDI number.

Thank you for your help. I look forward to your response.
