SCAM as mentioned above. When you answer the recorded message begins lecturing you about how they've been "trying to contact you" & this is your "final notice". I don't HAVE a credit card. I pressed 1 & asked for a supervisor - the guy refused & went on to say I have a "sexy voice" & he wanted to talk to me more. Yuck. I had to call back 5 or 6 times (as soon as I'd ask for a supervisor they'd just hang up) & was given another number to call with complaints. That number is 804-255-9490. The guy who answered at that number seemed far more concerned with who had given me the number than with my complaint & the conversation ended with him saying he'd put me on the no call list but he couldn't do anything about the rest without a name..... Nevermind that he was the only one who had even given me their name when they picked up the call.
I'm tempted to call them randomly & say some nonsense before hanging up - wonder if the irony would be lost on them?
Scammer wanting to lower interest rate what they want is information. Block number they will call with another one. At least you will have some peace for a little while.
