My electric company gave me a number (UID, not phone number) to resume a call if the issue wasn't fixed within 24 hours, and I'm pretty sure internet operators have the same protocol (at least used to).

What planet do you live on ?
Seriously. Where I am it is guaranteed that a utility company would never even consider such a concept let alone have the technical competence to actually implement it.
I'm jealous. ;)
Is that to restart the call to the same person or a case id that gives details of your request and that could be passed to anyone?
