Direct Express complaint: Account issues

In the past month and a half I have had various transactions being paid twice when the items I had purchased should have only been paid once. I have made numerous phone calls to discuss my account with Direct Express customer service (human). Each time I have placed a call after pressing numbers on my iPhone in hopes of getting connected to the human service department, an automated voice says that they are experiencing high call volume it then tells me to check my transactions on their website or call another time then it automatically hangs up on me. It doesn’t matter what time of day I have called. My debit card balance is getting extremely lower than it should be, plus I now have yet another transaction placed sometime between last night ( March 4th) and today March 5th. I don’t recall even using my card since March 3rd ! So I seriously need this issue resolved and soon before my balance is $0.00 I had a higher balance than I do now!
