They asked for the wrong person . It's a robo call is the first red flag . They called weeks ago and now they are calling again .  Scam  

Not true. A process server will never call in advance – that would just alert people that they're about to be served and allow them to skip town or otherwise dodge service. These people are clearly up to something else.

I got the same call and I asked them who they were they got mad.  I called back and their vm does not even state what company or firm they are.  A real debt collection agency would at least have a name and a reputable web site. Furthermore a debt collection agency cannot serve you lawsuit papers. Someone such as a constable or a sherriff from the county you reside in has to do it in person.

I say we just call them everyday and harrass them.  Or when they call just make weird noises into the phone.  Beware of numbers that begin with 844, 810, 991. Etc.....  These are all scam numbers and most of them are from India.  Some of them are even sending phony emails.

Well I'm glad I found out who these idiots are. I have been getting this 810-221-0268 number for over 2 months.
I called them today to find out exactly what the hell they are talking about, after months of voice mails being left stating "we are calling you about a complaint filed against you in our office" and want to give you an opportunity to make right and even gave me a case number LM22661
Well I called, first got a Tanisha, then by the third time got a Keith Edwards, that I have been harrassing all morning to get an address and name of his company.
Well finally got the company name out of him, as Recovery Solutions Group. I asked what type of Recovery, big mistake, he goes into a tirade about not giving me the company's address and fax number and what type of information that is about me. I keep calling back, he then proceeds to tell me, that he will not give me any more information, because I could be the uni bomber or some fanatic, trying to come to their offices and blow them up, and how could this number be dialing out because it's an automated system.
That was your first mistake buddy, because, guess what, you're being reported to the Michigan and Texas State Attorney Generals office.
Hmmmm, guess we was scammed, huh
