Cell C robbing their customers

Cell C's "one day" data is a robbing game. While other service providers give you 12 hours to use the data, Cell C data will expire at midnite even if you purchase the data at 23:30. On top of that, your anytime data continues to be chowed even when you still have daily data. When i asked them, they blamed background apps for the discrepancy. When i purchase daily data, expect every app on my phone to use the daily data.
