Hi Guys

I'm having a problem with my supplementary line, on April bill stated this number buying extra data for RM10. And now the May bill is out, shockingly it stated buying extra data for RM15 3 times, which cost me extra RM45 this month.

The problem is, the sim card is not even on the phone for more than 4 month already. The sim just active for few weeks only when got the number which is 5 month ago.

Anyone having this issues?
