You need to check your phone to see what apps are using up your data allowance.
Some phones have a data usage monitor built in but for others you can download free apps to monitor things.
If you contact 48 support they may be able to give you some info about your data usage (e.g. if it was gradual or used up in one big go or whatever).

Hope this helps.
