your phone company should be able to provide those, albeit at a cost if not free.

why they saying no?

and why do you need them? A pro se litigant does not issue out subs ... the clerk of the court does & you have to insure service is performed....quite a lot of information is required prior to a clerk issuing one out ~ they don't do this pro se litigants often.

Assuming you have a case filed somewhere.
