I'm a Digi Postpaid 50 subscriber, which mean all I have to paid is RM53 inclusive GST. But, since January 2017, there are unknown usage charges in my bill that cost me around RM70, which means I've to paid RM120++ every month. Initially I thought it is my overdue from the previous month, but after this extra charges repeat for several month until now. Digi please give a reasonable explanation or I'll consider terminating my subscription. Thank you.
