Just got a call from 305-000-9957 and pressed nine trying to get to a live person, but it just kept ringing. I am on a "do not call registry" too. If you are on the registry, go to www.donotcallregistry.com and file a complaint; I just did. I know filing a complaint works because I have had to do it with a couple of other telemarketers and the calls stop. They get fined everytime they are caught so be sure to file a complaint. It only takes about 2 minutes to do so.
Automated recording saying they can lower your credit card rates. I let the messege play through and got a live person. I told them not to call and to take me off their list. He said since I have a credit card they can call as many times as they wish and that if I didn't want them to call thney would cancel all my cards.
