Need advice for Accounts Payable Internship

I've been interning for this government organisation for over a year now. I started in IT and have transitioned into Accounts Payable. I'm studying accounting and they said Accounts Payable was the best position they could move me into.

It's been over a month now and they haven't taught me anything new and so far it's been data entry everyday. I almost can't take it anymore and I just asked to learn something new and the response has been "someone else in the team will do it."

I don't know if I should leave or stick with it hoping better things happen.
