I just got 4 missed calls right in a row (back to back to back to back). No voicemail message. I called it back and got a busy signal a few times and then a recording that the number is not working or something to that effect. Pretty sure it's some sort of telemarking BS. Blocking the number....
First ever such call to my cell. Recorded message offering to lower my credit card interest rates. I hung up before the spiel could go any further. I'm sure it's a scam.
