Few days back a collection agency called one of my friends and asked him regarding my information (name & address) so that they could serve me. They even left a docket number (which doesn’t exist). Last night I spoke them back and someone there said that they are going to file a civil lawsuit against me. I advised the person that SOL in CA is 4 years and that period is now expired. He claimed that they are still going to sue me. I have already checked my credit report and found that the misrepresentation of debt has heavily hit my credit report. What should I do now?
