This is a scam. The guy called and asked me about lowering my interest rate on my credit card and when "I lied to him"  and told him I did not have a credit card which I do have several (to see if this was a scam)  he hung up on me. I called the number right back 1-830-244-1718 it was disconnected.

This is a scam call.  They tell you they can lower your interest rate on your credit cards.  They actually can, but they charge an outrageous fee (hundreds of dollars) to do this.  Their ideal prey is someone with low balance, but paying an outrageous interest rate.  Thus, when you pay them the hundreds of dollars, they have actually cost you a great deal of money.

I just got a call from this number.  first it was an automated message about lowering my interest rate, so i pressed 1 to speak with someone, and when they answered i asked for them to remove my number cause i didn't know who they were and the guy just hung up on me.

I am on the do not call list and still get calls.    This one just called me and I refused to answer

I understand from the police, that it is not a good idea to call back on the numbers as sometimes it may conect you to an offshore number (original spoofed) and you may be liable for very high charges.  Just let it go.
