Will doing a chargeback on tuition hurt my chances at getting into the same university for grad school? I'm taking an independent phys ed course at my local university. I'm also currently studying for the GRE and I'm hoping to start grad school here in a totally different department in fall 2021. There's a professor I really like and have a good connection with here so I'm pretty set on this university.

The instructor cancelled the course after one class due to low enrollment, and the university is saying that since it started, it's too late for a refund on the $650 fee. I've called and tried to get a refund but their HR/registration department won't budge. 

I paid with a credit card and I'm considering doing a chargeback. Would this hurt my chances at getting into the grad school later on, and I should just let myself be robbed?

Practices vary, but probably not.


  Will it hurt me later on?


Very likely.  You probably will not be able to complete a graduate degree if the university thinks you owe money.


  I should just let myself be robbed?


No, you should insist on a refund.  Ask the instructor and their department to help you get a refund.  Ask the registration department again.  Ask to speak to the head of that department.  

HR is probably the wrong department to contact.
