hi, I need some help regarding my computer loan.
I’ve had this loan showing in my DBS account under liabilities for quite some time now (around -$1379), but there isn’t any clear info on how to repay it.
I’m currently in Year 3 and I want to start paying it back, maybe around $100 per month, but I’m not sure:
whether I’m allowed to pay in small amounts like that

and how exactly to make the payment (GIRO, bank transfer, or through a portal)

Has anyone dealt with this before or knows how the repayment works?
Thanks in advance!
