@Conxentra claiming the device doesn't itself do anything to restrict the device's use. Having the device in a network is what stops it being claimed elsewhere.
If a device is in a network that you don't have access to and you don't have any proof of the original purchase of the device, that device is now useless.
If you have proof of original purchase then contact support who can reassign it to your organisation.
Mad but true!
