Rogers data randomly stops working around 11am and doesn't go back on for 24 hours or more. What could be the cause?

Basically the title. Once a month (not usually around pay period, this is like a week after payment day, and usually happens at the start of the month) my data suddenly goes very slow/disconnects. My screen shows 2-3 bars LTE but I'm stuck on a forever loading screen. Then, after a day or two it turns back on. Why does Rogers do this? Help me.
