This place is a scam they call themselves Financial Mediation Group and they give you faulty number and give you an address to a vacant building and a drop box!

This number has called my husband on my cell phone 765-314-4362. They keep saying that he'll be receiving a summons in 24 hours and needs to be available at 9:00 am please do something thanks!

The person needing to "please do something" is you. You have federal and state laws to help you enforce your rights, and an address for these thugs provided by another commentor.

Whether you are called a debtor or some collector thinks you can flush one out, you have rights and options. Many are simple to exercise if you only learn how. You are entitled to proof of claim and fair treatment. If you get neither, the collection agency should *not* win your assets. You are granted control of how you are contacted, the right to dispute debt claims, and the means to sue violators at low cost. The FTC and the CFPB can start you on your homework. See also if your state laws grant additional or stronger rights.
