How to unsubscribe unrecognised purchased

RM0. You have been charged RM 3.9 for purchasing Apple MTFBFLQTQY from Apple. TQ for using Pay with Digi.

As stated above, I have been charged Rm3.90 for this month November 2021 and also the same amount for previous month. I just want to cancel it but I don’t know how and where since there’s no any history on my purchased history and I already cancel all my subscription in IPhone setting. But still, they purchased me RM3.90 every month. How to get rid of it?
