@academicalnerd thanks!
I went to university in the morning and was hoping to pay the tuition for the period 2 via online transaction and just follow up the finance counter for the updates of the exam permit in the information system.
Turns out my phone internet had issues but fortunately the finance office queue was short and I was immediately served for payment just 2 mins after entering their office.
The finance staff asked me if I can pay up to period 3 in which the amount was just enough for my wallet's cash. I paid all of it so I won't bother for it again during period 3 or the finals. Now the wallet is empty 😅
