I Accidentally Paid Gcredit, what do I do?

A lot was going through my mind, I was already paid with Gcredit but for some reason I processed another payment and I was charged on it, I don't have any dues on gcredit I just messed up because I'm going through a lot. Fully paid ko na pala to dati, akala ko parang may glitch lang kaya 0 nakalagay so I processed another payment on gcredit by inserting 2k amount manually. Can this still be back?
