For Wise and I noticed you are working in KL Sentral, great, because I work here too and you can always drop by Sam's Groceria to reload TnG and pay your bills. Remember to choose Groceries category.

For my Wise, I only choose utilities and groceries.
Utilities category is only TNB and Syabas. UniFi is not but you can pay in Sam's which I'm doing as well.

In short: UniFi, Telekom, Astro can be paid via ePay and TnG can be reloaded in Sam's. Split the payment to RM 50 per transaction and TnG not worth to split because each transaction incurs RM 0.53 of service charge. So, I always reload RM 100 or RM 200 one shot.

For Maxis, just use Maxis Pay and it will be under Mobile category and split into three payments.
