Walmart Money Card Labeled me a security threat when I have never done anything to them Nationwide

So I went to Walmart today and bought a Preferred Walmart Money card so I could order some parts I need for a desktop I am building and didnt want to deal with anymore banks today. I load up $500 and was told after activation I could reload another $500 up to the $1000 per day max. So I get home and activate the card...or at least I think I do. During the call I was transferred to the rudest, most heavily accented person I have ever heard. He was asking me verification questions but half the time it sounded like he was ordering Chinese or something. So I finish the verification and he says "please wait for activation" and then I hear "you're temporary card can not be activated. You will not be issued a permanent card." WTF I think...so I call up and to a supervisor who activates the temporary card and says I can use it but can not get a permanent one as I am flagged in Wa. Now Walmart's system as a "security threat" Now I have never done anything to Walmart other than when I worked with them temporarily in August 2013, and was asked not to return after I stood up to another temp worker who decided to get in my face aggressively and talk to me like I was an infant and stupid. I told him I didnt appreciate it and he needed to back off, at which point he decided to act like head boss in charge, even though he was like low man on the totem pole. I notified our supervisor of this incident and I was told not to come back. Now I buy a card and am labeled as a "security threat?" How is this even legal? I was also notified at this time to "never again buy another Walmart MoneyCard as the same thing would happen again." Can't believe this bs, but hey I am must be a "security threat" for standing up for myself...does that make the CEOs afraid too?
