Recently, my 87-year-old father received a pop up warning on his computer that it was infected and that he needed to call Microsoft right away. My dad called the 800-number and was told that his computer had a virus and that they could repair his computer if he gave them two payments of $499.99 and $249.99. My dad, believing their story, gave Zeniff Services his credit card number. Soon after, my dad emailed me to let me know and I alerted him to the scam, but it was too late. We called his credit card company that night and said we wanted to cancel the charges. We were told that we could not cancel pending charges (and that did not make a lot of sense to me). Then, they told us to call Zeniff Services to tell them that we are not approving the charges. Well, we did (knowing it would lead nowhere), and left a message saying that we did not approve the charges for $499.99 and $249.99 the day before. That did nothing, so then we called the credit card company again a few days later and asked to dispute the charges (explaining the scam). Five days after we called the credit card company a second time, the dispute was denied and the charges were validated. My dad had to pay $750 to scammers, even though a major credit card company certainly knows this is a scam. How are credit card companies not helping put these scammers out of business? Are they getting a cut? And how am I not able to immediately cancel a charge on my credit card when I called the credit card that night? Credit card companies need to do better. But beware of these Internet scams. As I told my dad, Microsoft will never pop up on your screen. They will never email you asking you to call. They will never call you (as Zeniff continued to call my dad for days, trying to get more money).
