Hi ​@Arennie there must have been some usage of roaming for you to be charged for this. A lot of apps can use data in the background, so if roaming was enabled, you would have been charged only if the services were used.

I didn't use any it showed me on the app it wasn't used 

Ah my apologies ​@Arennie  I had mis-read the situation. You had purchased an add on but it had not worked. I am sorry about this.
