I am expecting 1299 billing per month, upon installation we have paid 3999 including those gcash application, activation, etc. I need to know what are the details of that 3999 whether it includes the one time payment of installation and Modem. Because this month our bill reaches to 2096 and I don't know how it happens. Or is it possible that I have data excess from allowance that cause extra bills. Maybe I just need some clear details about our bill thanks.
