I've gotten this same message from various numbers...'opportunity' to lower interest rate on credit card if I press 1. I also am on the do not call list, but it doesn't seem to matter.
I keep getting calls from these idiots for what seems to be over a year now. I have reported them on several occasions. I believe that the do not call list is just a huge list for these type of people to to purchase. I have all these numbers from "Card Services". Put them in to block list, I use "Extreme Call Blocker" for Android. https://play.google.com/store/apps/details?id ... a25vbmRyb2lkIl0.
