The Issue
Telco C advertised a roaming service so customers could use their mobile service while travelling overseas. Customers could select the date range they wanted and then pre-pay a daily rate for all mobile calls and texts and a small amount of data each day for that period.
Some customers who signed up to this service contacted us after receiving unexpectedly high bills for excess data. They said they understood once they used up their daily data allowance the service would stop working and then reset the following day.
