I was billed to renew Micro Trend antivirus on 2/6/18 and 0n 2/8/18 for the same ting micro trend yearly service. I was billed twice for $114.00 and 107.00 and I should not have been billed twice for the same yearly service. It appeared on my American Express card. What do I do? Whom do I call to get straighened out?
