This number called my mothers phone and left a message stating if an Alicia Taylor did not return the call in 2 hours they would continue with legal measures. That legal documents were refused to be signed for.
Yes, it is a scam. No REAL process server is going to call you in advance; you could hide if you knew they were coming. And you can't buy your way out of a summons, either, which is what they will claim if you speak to them. My advice is to block the number or at the very least, ignore them when they call.
