I have a prepaid Visa debit card through Walmart. I checked my card balance today and saw almost $150 worth of charges I did not authorize. I've already called customer service to report and and canceled the card. They say it'll take about 10 days to get the money back. TQC, has this ever happened to you? Did you file a police report? I haven't yet but will be first thing tomorrow. Is there anything else I should do?
