Hello guys, i am new on unifi prepaid, yesterday 23/4/2023 i purchased 8gb of data for RM18. But minutes after the purchase, there were 3 additional charges on my account.
I contacted unifi live agent for support, they told me they were sms changes and their system show the sms were send to those 3 numbers.

The thing is i never sent any sms or made any call. There were also no records of my phone sending any sms. You will notice that the 3 numbers are almost identical and only 2 or 3 number apart from each other and they are send almost exactly 15 minutes apart from each other.
I told them i didnt send any sms and there is something wrong with their system, they say they will investigate and get back to me.

Anyone experience this with unifi prepaid? Is their system even secure?

Below is the time line.

8.45: Purchase 8gb data from the unifi app
8.47: Receive sms from 61000 informing me i have successfully bought the 8gb data
8.49: first sms charge
9.05: second sms charge
9.20: third sms charge
