oh my god, I've been using umobile postpaid for so long, and now suddenly they double charge me for my October bill. When ask them to deactivate their stupid technical error for activating ub20 onto my account, then they come up with tones of excuses and forced me to take the ub20, but when insist on canceling it and waived the charges, now they suddenly said my 10 days usage is double of all the months i've been using.
