John Peters from Greenberg and Associates called trying to tell me he was from a process serving company and he had paperwork they needed my signature. He advised me to call 949-371-5076 with a case number. These individuals are hella fake.. Refused to give me their Ubi number and proof that they were able to make these calls within the state of Washington.. Called from a blocked phone number....and immediately hung up when I asked him for his manager. I was a first and third party debt collector for 15 plus years and these are Phantom debt collector tactics probably calling on purchased debt from 20 years ago of which statute of limitations has for sure run out. DO NOT PAY THEM NO MATTER WHAT THEY TELL YOU.
