If your educational institution does not accept the demand letter, it's crucial to first understand the reasons for their refusal. It could be due to discrepancies in the loan amount, payment schedules, or specific terms that do not align with the institution's policies. Once identified, you should facilitate communication between the lender and the institution to resolve these issues. This might involve revising the demand letter to meet the institution's requirements or providing additional documentation to clarify the terms of the loan.
