Could you tell me if it is natural and correct to say rig one's data expenditure meaning to make it look like someone spends more than they really do? For example:
The customer accuses the service provider of rigging his data expenditure. He says he spent 20GB of data last month and an app on his phone backs it up, but the carrier says he spent 30GB.
If it sounds off, would you tell me how you would say it?
