Credit Card Interest Unwanted Robo Calls

Multiple Calls daily, I've asked repeatedly to be taken out of their computer call list with no success. I just called the number that called me & actually got a VM asking to leave a message- I screamed at the top of my lungs. Let's see what that does. Next time I get the boat air horn (buy them in WalMart- will blast eardrums!) Was having the same problem with the people trying to remotely get into my computer about a year ago & managed to stop them by screaming "[***] YOU" repeatedly into the phone after MONTHS of multiple daily calls & discussions with callers asking them nicely to remove me, then threatening them with the law. This may not work with this bunch, but at least the extreme reaction back gives me an iota of satisfaction. I don't feel sorry for the callers- they CHOOSE to commit fraud. They deserve the abuse back. Since the people who are supposed to stop this can't seem to, I'm taking it on myself.
