This is a third party debt collection co. They leave one of those "if you don't hang up in 30 seconds, you verify it's......"  And then when you call back to tell them it's a wrong number they ask for you.
This is ILLEAGAL!  Save the voicemail!!!! Get their full name and address, and contact your attourney, od a debt resolution company to file suit against them. They are in violation of fair credit collection laws and you can sue them for $1000.... Call a debt relief co. If you don't believe me....but pass along the info if I'm right

Received a number of phone calls from First Credit Services. They say in every phone call  "if you don't hang up in 30 seconds, you verify it's. I finally talked with someone on the other end of the phone and they refuse to mail me anything showing I owe someone money. Also they will only take a payment over the phone and refuse to take a certified check.

Calls about 5-6 times a day can never get a person when you are given a 877 number to call back. I too get the hang up in 30 seconds  if you aren't who they are looking for. This is [***]

Signed up on credit karma to see what debts I DO owe, and the charge they listed was completely bogus. Glad I didn't pay.

Just got a call from this number yesterday. Always leave the same voice mail "if you don't hang up you verify.." That doesn't verify anything, it's so stupid they wouldn't know if I even checked my voicemail! (It's not a recording saying it it's an actual person) I just add the number to my blocked caller list.
