There are more perinate matters to consider than the plain simple matter of boundaries and cost / payment.
The account holder is legally responsible for ALL INTERNET USAGE over their service. If this third party were to be granted access to the internet connection and they then make abusive / inappropriate / illegal use of the service, it will be @DAVID3370 who would face prosecution.
This is more that the consideration of "not being cooperative" it is the right and proper protection of self from the potential liability arising from a third party's (mis)use of a service for which one has contractual obligations...
