Frustrated with University of the Cumberlands

[CollegeStudentAC]

I am asking for a proof of enrollment letter that also states my enrollment date and not just the term as after 13 weeks, I'm able to withdraw from my RESP without limit but the person refuses to provide that. I've only been enrolled in one college prior and that was a private for-profit college and they provided the date (without me even asking) but regardless, I really don't see how my request is unreasonable. I would love some input because I am very frustrated.
