They called and said they were from my Canadian bank and that my VISA card had been used for a $300 eBay purchase and an $1100 western union transfer. I could barely hear them because of static and thick accents. They asked me to go to my computer and press the Windows key, which was super suspicious. When I asked whether they could confirm that they were from my bank, they gave me a long scare tactic about how the RCMP has been notified and fraud is very serious and we don't want to alert the fraudster. They could only give me the first four digits of my card number, which is common knowledge for each bank. I found this very suspicious and they hung up on me.
