Another victim here. I never been charged with data roaming fees when I was abroad with my data off.
In 18 Mar'16, it was my first time getting this charges then followed by 26 Mar'16 when I was abroad.
My line get barred then i have to pay the OUTSTANDING amount to get the sevice back online.

All the rubbish reasons given like what other victims shared here when I complain to CS. THE PROBLEM IS I WAS USING THE LOCAL FREE WIFI SERVICES, NEVER TURN ON THE DATA ROAMING BUTTON!!!! How it work when the button is off???

I think with this level of fraudulent data roaming charges, it's enough to make Celcom another spot light soon after Maxis if they failed to settle this issue wisely & professionally
