<prompt> Human: I received a text saying Dear name, There is an important issue regarding your card ending in . To avoid a temporary hold being put on your account, please call 8006443423 immediately. Card ServicesAfter calling the number, they wanted me to enter my old pin number and change it to a new pin number. The card was a Visa credit card but I dont remember setting a pin number. There was also no mention of my credit card company. I entered what I thought might have been a pin number and then entered a new one. Is this legit or did I just get scammed?  <response>: Never call a number anyone sends you. Call the number on the back of your card and ask about it.
