Direct Express complaint: Dispute denial

I am if you do $999 on the 3rd of every month from Social Security put on to my direct express account on the 6th of the month I went to try to withdraw my rent from the ATM and I had insufficient funds I came home to call and find out why because I don’t have online access or a statement sent so I got on the phone with them they said there was a pending charge of $500 to GameStop and multiple other charges that I did not authorize I tried to dispute said that charges they said that I could not because they haven’t cleared the account yet so I called back 2 days later to dispute the charges and they told me that I had to write out what happened and send it into them within a 10 to 10 business days I did that on the day that I sent the paperwork they had already denied my claim. I made them reopen the case saying that I had new information because I did I got transaction ID numbers and names and dates of the transactions which I didn’t have previously I faxed in that information to them and they denied my claim again saying there were discrepancies in the investigation findings and that they sent me a letter saying what they were quite clear these are not my charges I’m being kicked out of my home I have no money for food this is my only income
