I received a call from this number when I said hello  this woman started saying I won multiple gift cards for different amounts. She never stated who she wanted to speak to or stated where she was calling from  then quickly needed me to verify my info so I hung up.

When I picked up, I got an automated message saying they were my credit card company and they would help me get lower interest rates. The message didn't specify which credit card or what company. When I selected the option to take my number off their list, the call immediately disconnected.

Same thing as Jane (above). They left message saying that they were an unnamed credit card and wanted to lower my rate. Good thing I checked here. I believe a bank needs to disclose its name when calling you.
