Who called from 3238860644

Call this number within two hours to find out about a case against me. I was being sued by someone and this 'lawyers' office would be able to give me more info and our next court date

I received a blocked call on my cell phone they gave the call back number of 323-886-0644 gave the company name AC Services it was in reference to my husband when I asked how they got this number they advised my husband had it listed as an alternate contact number they provided me with a case/reference number and indicated my husband needed to call within 2 hours to avoid legal action

Left a voicemail that said to call back within 2 hours.  Said they tried to deliver legal papers and were unsuccessful.

Just got this call.  Im worried that it is a scam but also worried it's something I don't know about.  have you heard anything else from them?

ACS. Voice mail said legal papers refused to sign for. Call this office within 2 hours. Gave reference number.
DO NOT CALL THEM ITS A SCAM!
