Daytime data being consumed instead of night time

I am very disappointed with telkom. I have heard people complaining about how they rob you when you make use of night data and it would instead consume from your day time data, and now I have expereienced it myself.. I have tried 3 times to wake up midnight and download movies, and everytime when I check my balance the night time data will use very little but the day time will be depleted? This is *******!! If this is how telkom does business I sure will not be renewing my contract with them. Everytime I plan on using the night time data, I make sure I restart my router first, but even after doing data it would use up my day time data. Please fix this asap. I will await your call. Please call me on ***
