Don't know who this calling my phone, but calls all through the day.

Looking for some one that does not live here

Left a threatening phone message about a case number regarding an incident.  Have know idea what talking about.  Said an attorney and was going to make a final decision if i didn't call back today.  huh?  had a case number, hard to understand... May have been a debt collector, unsure.

The lowest of the bottom feeding collection agencies.  You can't link their phone number with a business website or contact.  Real shake down types using scare tactics... stand your ground against these people.  Next stop for them is probably looking for coins left in the vending machine

Libby up there gave us a hint this might be Commercial Recovery Systems / CRS & Associates in Dallas, Texas. Known lawbreakers and apparently more active recently.

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 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.
