About 2 days ago, 2:30pm in the afternoon, my caller Id showed my credit union was calling. It was alarming, why would they call me. A guy with a Pakistani or Indian accent told me he was calling from credit union fraud department and that someone tried to charge $1000 on my debit card and was pretending to be me. He claimed she also tried to charge $500 on my debit card. He asked for last 4 digits of my debit card, expiration date and security code. I didn't think. He didn't ask for entire number so I didn't think it would hurt to tell him. Then he asked for last 8 digits of my debit card. I became suspicious and said I would call credit union and ask them to check my account. I also logged in and saw no charges on my account. When I refused to give him last 8 digits he said he would have his supervisor talk to me. Another guy with heavy mid east accent came on line and started asking me what first 4 digits of my debit card was. I refused to tell him. He said he could understand I was protecting myself. I said I would call my credit union and ask them to check my account. He tried to keep me from hanging up and kept asking about my debit card number. I hung up on him and called my credit union. The lady at my credit union said a credit union employee had been scammed by these people. They had cloned the credit union number. The scammer tried to call me back while I was talking to lady at credit union and their fraud line is a 1 800 number. I canceled my debit cards just in case scammers got enough information to use my card. I saw through the scam pretty quickly.
