It's Cardholder Services again; do yourself a favor and get a call blocker device.  For around $50 you can get one that will hold around 1500 numbers.  Check Fleabay, Amazon, etc..  Then all you have to do is hit the blacklist button (or manually enter the phone number), and presto, there will be no more annoying calls from this number.  The FCC and the do not call list are a joke, don't waste your time.

Got call from same number. I'M TRULY F****NG TIRED of these telemarketers calling and harassing myself and my family constantly. And that b***s*** "Do Not Call" registry is a f****ng joke. Useless. Advised family for all to purchase an inexpensive bullhorn, football coach's whistle, or an air horn and when these soulless excrement call to let them have it. And I pray that this blows their eardrums.

Got call on my cell phone. Did not answer and they left no message. Apparently they are robo calls as I have given out my cell phone number only to a very few people.
