Green Dot Bank complaint: Unauthorized purchases not refunded

I received a phone callFrom someone stating that they were from greendot.com asking me if I had made a purchase at Walmart in Crescent city California for $84 I said no they then told me to check my text messages and to follow the instructions.. they have done this in the past and I tried to send the code that they sent me but it wouldn’t go through so I tried again it didn’t go through so I hung up this scam could only have come from someone inside of greendot.com because the text message cameOn the same account that I was sent in previous dates from Greendot.. Greendot sent me an email on the same day Tellingme A ation that I changed my email address but if this wasn’t me to call a number.. I never read this email until a couple days Had passed.. When the person changed my email they change my username and password to my account and so therefore I was locked out of my account and on the same day there were two charges and two refunds to my account and they emptied my account..
