The left a message for a Jamie Hines. Said they had 2 hours to call back the legal company they hired to serve him the papers he refused to sign for. The number came up restricted on my cell phone. Last time it came up restricted I answered and no one spoke.
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.
