Direct Express complaint: 50 days since disputing unauthorized transactions

I was checking out using my direct express card the cashier said declined call your financial institution Went to ATM received the same message. I called direct express immediately Representative said DIRECT EXPRESS blocked my card due to suspicious activity. Went over transactions there were over 2,000 dollars in unauthorized purchases. That started the dispute. Received a letter from Direct Express stating the amount of the transactions etc. I call every day you cannot get through and speak to anyone ever. One time in over 50 days I have spoken to someone in the dispute dept only was told that it’s in review. Direct Express are the ones who caught the suspicious activity and blocked my card and I am still waiting. That is a lot of money. I went on Social Security’s website there are so many complaints about the same thing. This is terrible I am a single parent I have never had any problems with any of my accounts if there is a problem this is absurd. It’s been over 50 days.
