What is the expected time for "promptly furnish"?

IL Trust Code states "the trustee shall promptly furnish to the qualified beneficiary a complete copy of the trust" upon request - How many days after a request is within reason of "promptly furnish"? I know the trustee and their lawyer have it and scanned. I have been asking for a copy for weeks now and the trustee either ignores my follow ups or comes up with an excuse.
