We recently had a trip to the USA and returned home to see multiple roaming charges. It appears from the bill that we received or made phone calls to trigger the charges, out of the dozen or charges I could find two calls that line up with date and times. There were multiple charges one my wife’s phone whee she didn’t make calls those days at all. Not only did she not make calls on those days but the times involved were past 1am when we were sleeping.
how do we go about having these charges investigated?
