<prompt> Human: I partially fell victim to a 2 part scam over the last few weeks. I got a call from a courier with mystery papers that was supposed to deliver something during hours I was needed at work. They needed to much PII to deliver and I told them I didnt talk to scammers and hung up on them. I had a message from them that they were not a scam, and that the people who were trying to send the package could be reached at X, case number Y. I had no idea what anybody could be trying to send me, but made the mistake of calling the number the following week. When they answered, I gave them my case number, and they needed to verify my identity. They had my full name, asked for my DOB and last 4 of my social. I stupidly gave it to them dont do this!. They then told me I was being sued for defaulting on debt, and referenced a real account I had with Wells Fargo a decade ago. They said I was in default 400, but with interest and fees the amount was 2500. They said they had sent letters offering to settle the debt for 700, and that I was being served papers. I told them I didnt have any debt true and Id happily see them in court if I was summoned correct answer. Stressed out, I started to do research on how and when debt collection works and read that if you refused a summons, even in delivery of the paper, you would get a default judgement against you. As the debt was B.S. I called the number back to ensure that I received my summons, as I didnt want me blowing off the courier to be construed by a court as something that would lose me a case automatically. I was told Id be served by the Sheriff that day or the next yesterday. So now I have to tell my wife to expect a police officer, joy. The next day, I start to do some work on researching this company. The company was Z dont know if I can put it in here so I wont but upon doing a Google search, I couldnt find it. On looking up the phone number on Google, I couldnt find it... Okay, this is beyond fishy now. I spoke to about 7 people trying to get an address to confirm this place, but no one would give it to me. I finally called back and asked where and how much to make the check out to... they gave me the address of a Regus office. For those of you who dont know, thats a place where you can rent an office... for a day. I even called the Regus office and confirmed no such company was renting that particular space.So... I am now 99 sure this was a scam. If I get summoned, Ill know it wasnt and will update, but the amount of stress this has put me through this week is sad.I dont know if their endgame was to get me to settle the debt very likely or if their endgame was to get some PII for ID theft reasons. They did weasel my date of birth and last 4 of my social security number out of me.I have called my bank, and done a credit freeze through all 3 credit reporting agencies. I have confirmed with my bank who also provides credit monitoring service, that the last activity was 4 months ago... when I changed cell phones.In any case... I hope someone learns something from this, but if you have any advice Im all ears.  <response>: DOB and last 4 of my social. I stupidly gave it to them meh most people probably already have this sort of information. I have scammers that leave this info on my voicemail to prove they know its me. So I call and ask them for my whole social and if they dont have it, I hang up and block the number lol.
