Direct Express review: Unauthorized purchases

On 9/21/25 I checked my account to find over 2000.00 missing. I looked at the transactions, they were for several restaurants, a hotel, many door dash orders, an online adult products store x rated, and several transfers to a prison account and a grocery store that is not even in my area There were 40 transactions.. I called Direct Express to report the charges, I sent in a detailed list of fraud charges, was told it would be investigated. I waited 10 days and called back to check status. Was given a partial refund. Today I received a letter stating that these transactions were authorized and had access to information only I would know. They said the merchant was pre-authorized to debit my account. With no signs of compromise, plus a review of prior transactions with the merchants confirmed the transactions were authorized. I received three letters all dated and mailed the same day. Impossible. I live alone, I have never given any information about my card to anyone, My card is always in a secure place, and I only use websites that I have ordered from and trust. I am 76 years old I am extremely frugal, and seldom travel. I don’t know anyone in prison and I have never used door dash. I tried to use my card today and it is locked and restricted. I can’t talk to anyone on the phone as it is Saturday and the website says it is having issues. Now what am I supposed to do to do? I have already changed my SSI deposit to another account. Someone has stolen my money and I am angry.
