I am currently using a Blackberry. Note, this isn't a new phone and I'm not using a new plan; I've had this plan with Koodo for months now. Mostly, I use data for bbm and email (text only). I am being billed for data which I did not use. I checked my usage and on some days, it states that I have used as much as 400 mb. At the times which this occurred, the data is being used at the same time every hour. I do not know what is causing this, as this situation has never happened before. I am wondering why Koodo is charging me for data which I have not used.
