So today, I looked on my door and seen a notice of pending action service of process... The paper has no information on who sent it, no address, email, etc. All it has is a phone number and it says that when I call nobody will tell me what I am getting the notice for over the phone for safety purposes. What's even crazier about this notice is that it states that I have only 1 day to call to "schedule and appointment" and if I fail to do so, I am interpreting my intention to resist or oppose service of process.

Ive read around on this site that a few people from my state (MI) have received these notices on their door for credit card companies, so I assume this is what I am receiving one for but I am unsure. Can anyone tell me how to go about this or how to figure out what its for?
