This number has been calling my brother and sisterbut they ask for me.  Very harassing the only info given is that they received a complaint in there office and you will need to call to stop further action against you. If you can't be reached at your home they will try to reach you at your verified place of employment.

This appears to be a "Fake Process Server" scam which is often a lead-in for a "Fake Debt" scam.
There are no letters, papers or documents, no court cases are going to be filed and no assets are going to be seized.

The message they leave is intended to instill enough concern in the intended victim that they will return the call.  The goal of the scammers may be one or more of the following:

• They may just be phishing for personal information, under the guise of verifying your identity, so they can use it for identity theft later.
• They may claim that you need to pay "processing fees" before they can serve the papers.  Payment could be demanded through gift cards, cash transfer apps, or by requesting bank account information.
• The scammers might use this as a pretext to a "Fake Debt Scam" and will claim that there is some outstanding "debt" that they are trying to collect on.  The claimed debt will usually be very old (beyond the Statute of Limitations) and a fairly sizeable sum.  They will offer to let their victim settle the debt for a fraction of that amount and avoid being sued in court if they pay then and there over the phone.  They will be very aggressive and try to browbeat and threaten the victim to make a payment.  They will refuse to give any details about the debt beyond generalizations and will also refuse to agree to send any documents supporting their claim, often claiming that they were already sent at some earlier time.

Relatives of the intended victim and even employers (present and past) may be called in an effort to embarrass the victim into calling the scammers to get the calls to stop.

The best course of action is to ignore the calls and not return any call.  If you have any doubts about being sued, call your local courthouse instead and have them check if anything has been filed against you, you will find the lack of results reassuring.
Remember that if you were really being sued, a real process server would not call you or a relative about papers needing to be delivered, they simply show up and serve the papers.
