Maya 10% Interest Boost using Grab deposit Hack question.

So, i read in another group that the Maya 10% Interest Boost is still working.

I Transfered ₱35,100 from my Maya Savings to my Maya Wallet. Opened my Grab account, and linked my Maya Electoric visa card details.

However, when I tried to deposit ₱35,100 to my grab, I Got this message. ₱35,751.00? Saan galing ang ₱651?

Need help sa mga nkagawa na neto pls!
