Monday, XX/XX/XXXX my husband receives a call saying they need to know if we will be home between XXXX and XXXX the next day because they had been hired to serve papers for a complaint. My husband did not get the whole number but said it called from one number but said to call an XXXX number to talk to the lawyers about it. 
Tuesday, XX/XX/XXXX I went back and checked my voicemail and on Monday XX/XX/XXXX at XXXX I had a voice mail to call XXXX although the call came from XXXX. I first tried to call the XXXX number but it says it is a message service even though the process server company is not same one that called again later. When i called the XXXX number i first talked to an operator that said he would have to get me to someone else. not that it matters but the person that called my husband and the one that i first spoke with did not speak clear english. I was transferred to XXXX who said she was with XXXX, XXXX and XXXX and they were hired by Speedy or Rapid Cash to collect on a loan I had in XXXX and that I paid it fine until XXXX and they never heard from me. Asked why I did not hear from them personally to verify I even had anything, she said they sent it to an address which i havent lived at for at least 6 or 7 years. My mail would still have been being forwarded at that time. When I told her I was leary because of things I had read about a scam going on she said if i wanted to resolve it she could get the other company on the line and I could settle with them without it going to court or being served. I questioned several times and she kept making it sound like already filed with county then I would say then the other company wouldn't be able to settle anything with me. Told her was interfering with my work trying to do anything at that time of day and she gave me the number to call back of XXXX and to just ask for her. When I called back I told She ended up saying well I had 30 days and I could contact Speedy Cash if i wanted to XXXX them. I asked again if it had been filed with the county and she said no but it had been given to process servers. She later contradicted and said I wouldn't be served if I took care of it in next 30 days. 
Wednesday XX/XX/XXXX : My sister texted me that she kept getting calls that a process server was going to be serving a complaint that had been filed against me and would i be home between XXXX and XXXX her calls were from XXXX and XXXX area codes. She has since blocked those to see if they try others. I soon after received a call from XXXX process servers who said they were out of XXXX, AL ( which is where I live ) and that they needed to know if i would be home between XXXX and XXXX because they had a complaint to serve me. The only address they had for me was my home. I did not give them any info even whether I would be home during that time or not. he called from XXXX which again when I called it had the same answering message that says this is only a message center. When I told her she said I had 30 days to resolve or dispute before any thing filed he said oh well give her a call and i'll put this on hold. 

I have sent an email to the company Speedy Cash and have not heard back. This is after googling their phone number and address. I just felt like too many red flags and don't recall owing any past loan from Speedy Cash or Rapid Cash. 

If it is a legit company trying to reach me I don't understand why they keep calling all these other folks when I have already contacted them. There is no XXXX process server company in XXXX Alabama and when I googled the XXXX number and XXXX, XXXX and associates it comes up with complaints filed with XXXX robocaller and another site that actually sent this link which I did verify legitimacy. 

I feel like someone has retrieved info when I have applied for a loan online and using the contact info. I don't know.
