Final answer:
The statement is true; it's standard practice to recontact refused Network Service Providers due to No Contact before resorting to an Unlisted Service Provider.
Step-by-step explanation:
The statement is True. When dealing with Network Service Providers, the protocol typically dictates that any providers who have been refused due to No Contact must be reattempted before proceeding to use an Unlisted Service Provider. This process ensures that all potential network options within the established network are fully explored and utilized before seeking alternative solutions. This is standard practice in many business scenarios, especially in service-oriented industries where network relations and provider communications are pivotal to operations.
In the context of network service providers, the statement is true. When attempting to contact a network service provider but receiving no response, it is important to make a reasonable effort to recontact that provider before considering an unlisted service provider.
This practice ensures that all known options are exhausted before resorting to an unlisted provider. Recontacting allows for the possibility of the initial contact being missed or overlooked, as well as giving the provider a chance to rectify any issues that led to the initial refusal.
Using an unlisted service provider should only be done when all efforts to contact the known providers have been unsuccessful or exhausted.
