Received call at 9:15 AM (EDT). Call I.D. showed: "HENDERSONVILLE, NC". Since I live in the area I picked the phone up. A robo announced my credit card limit would be lowered unless I "pressed 1" and spoke with a representative. I have no credit problems and hung up. I tried calling the number back several times and only got a busy signal. I feel it's a scam to get credit card details.
