I rcvd a call saying they would be delivering a package btw 12-4 I hung up in their face then got a call right after that was a private caller

Just got a call from this company.  They left a voice mail saying they would be making a delivery on Monday between 12 and 4 pm.  I would need to have ID available at that time.  I called back and they would not give me any information. I did not tell them my name but just asked generic questions.  They said that they are out of Dallas Texas and they would not give any further details besides this.  Scam or Creditor?  I called my county and there have been no court cases filed against me and by law they need to file either in the county you reside or where the action took place (if it's in the state). Love these bottom feeders.
