Never let bullies on the phone confuse extortion with debt collection. Honest debt collectors do not typically send their claims straight to a judge, and they don't take your ransom money to broker quick deals with so-called "process servers". There are no secretive "arbitrators", "mediators", or "prelitigation specialists", only sweaty criminals with a script full of bullying remarks. Lawful debt collection is a process, not an ambush, and you are due a chance at each stage to raise a dispute. The agents' horrid threats are empty and their conduct is illegal. Do not reward lawbreakers with your money. Challenge them always, sue them if you can.

This company named United keeps calling everyone in my family saying they are trying to find me to serve me papers and they change their reason why every time they call.

Left a message on my cell phone at 7:20am  saying they were going to serve me because I was listed as a reference for my brother (who lives about 3000 miles away!).

Called looking for somebody about a case

Received a private number call on my cell looking for some other person and they said to call this number about some case. His name was Charles Manual. Seems to be fradulent. I called back on land line and it appeared to be a private phone number.

got a call from this #..... Dont know that its about.
