Direct Express complaint: Unauthorized transactions

I noticed money on my direct express card not reflecting amount correctly… I have been locked out of my online account for Three years now… Called ,for support three times no resolution… So i called and asked for six months of my statements
I went through each month and was alarmed at all the little unauthorized transactions happening every month… Apple…Amazon….Unauthorized transactions happening in other states as well as department stores that i have not ever been to…so i called to dispute 6 mos worth of unauthorized transactions…I had to get a new card and pay for the card$13.00 and that was my free card a year…Had to pay to have them send it to me
Did all this and wrote my own letter to direct express for provisonial credit…Direct express does not send dispute paperwork untill after the !0 day deadline they require for all youre stuff to be turned in back to them to get provisional credit…They gave me a credit of $298.00.. That did not add up in my records to the same amount…Tried 6 times to get ahold of somebody to ask what to do… 56mins 89mins 62mins for six days in a row no answer…I finally got ahold of someone and they told me that if direct express deposited this amount then they probablly went threw my records and found that amount to dispute..At that time i asked to have the whole year of statements sent to me…Went through the whole year and found almost $400.00 of unauthorized transactions..Every month there was one or two unauthorized transactions..called back to dispute $104 more dollars…When i was going through every month with customer services there would be two or more that were unauthorized one being disputed and not the other ones on same page of statements? did everything they told me to do..wrote another letter of dispute and have been waiting over 60 days for answer or money to be returned..I called my card 2days ago and it had a negative balance of $298.00 They took the money back that was stolen from me..Spent 85mins on phone to be told that the investagator did not have enough information and closed the investigation and took money back.. I asked if we could open another dispute.. He told me no… This dispute is closed and there is nothing i can do about it…I get $918.00 a month SSIdisabilitey..On december 1st i will be getting $298.00 lessit is christmas.. I have one child who already lives a life of barley making it..because we barley make it…i have a set amount to live and i do not know what to do…This card company let unauthorized transactions happen every month for more then years and did not protect me the card holder…And now they have literally stolen money from me that was already stolen once before… Please HELP ME
