<prompt> Human: Im baffled...absolutely baffled. This has happened 6 times to me in the past month. I bank with BOA and on July 31 I signed into my online banking and noticed something strange. There were 4 ATM transactions made over three days in increasing amounts. One was a cash withdrawal for 40, the second was also 40, the 3rd was 50, and 4th cash withdrawal was 60. All of these cash withdrawals happened at the same Bank of America ATM in my city. My card was with me this entire time and nobody knows my pin but me. I called the fraud department and they were able to look up the transactions and see that a PIN number was not used. They issued me a new card, then it happened again within 2 days. 2 ATM cash withdrawals were made for 60 each this time at a different Bank of America, but both cash withdrawals happened at the same bank. I reported to the fraud department again and they also noted that a PIN number was not used. My question is, how can someone withdraw cash from an ATM without my PIN number? I can understand how my card could have gotten skimmed but wouldnt they need to physically enter my PIN number to withdraw cash?  <response>: I really dont know, but Id switch banks asap honestly.
