To further add...based on the comments above...I found this on the internet: https://www.inspirahealthnetwork.org/?id=5282&sid=1
Seems to me their number or name has been spoofed, as I don't know a medical center that would call and say they can lower your CC interest rates. I wonder if the company in NJ is aware of this. For the record, I live in Los Angeles. A doctor in NJ would certainly not be convenient.
Just received a call from this number. Didn't answer cause I didn't recognize the number. Didn't even leave a message. Tried to return call, but all I get is "The person your trying to call is busy, please try again later". Let's see if they call me back again. This time I'm going to forward calls from this number to my secure SAT phone and have COMMS center track the number. Will update this if I get something. Wouldn't be surprised if location is in a 3rd world country.
Just received call. Caller I.D says Inspira Woodbury. Once they said this is a call from your credit card company, I hung up. So much for the Do not call list.
