I liked Venmo and used it many times to pay people. One day I got an error that I couldn't send my payment to someone. I contacted customer service and they said I raised a security flag and they cannot tell me why. I was gonna let that go then a few days later I asked if perhaps I had spent too much money and they replied no and that if it happens again not to use Venmo anymore. What the heck is that all about? I am a law abiding American citizen there is no reason for me to get flagged.
