Hi..me again. I just found this report on the Better Business Bureau (BBB) web page about these "lower your interest rate" robo calls. Apparently it is a serious problem. Here's the web page for the report.
I got the call to. But I have a Digitone Call Blocker so it hangs up on them even before my phone would ring. The Blocker stores the numbers so I can check if I want to see who called. You need to get one also.
I got the same call about 4 hrs ago. I have blocked this company "card services" 6 times on my phone and they keep changing their number. I am on the do not call list and have reported them many times but nothing is done about it.
