After two years, why can't the Army's HRC (DMDC) get their logon problems solved?

Two years ago I got locked out of my VA account because I was using my Login (DMDC) account, finally I was able to get signed up with ID.me, now no problems, but still cannot access the Army's HRC to update DEERS or access my military records. Two years ago I spent money and time (live in Denmark) to call DMDC on the west coast, put on hold for almost an hour, talked for an hour, finally getting to talk to a supervisor. She told me they knowingly accepted a flawed system in order to get it online. They knew the new system would only support a select few country's phone numbers. Yet after two years it is still the same. I am lock out, unable to update DEERS or access my military records. I can access the VA, SSA, MY PAY, my two state side banks, even my State's official site (Idaho). They all contain sensitive information. Many of these sites use an email for security verification, so why can't DMDC get their I.T. department in gear and get their system fixed? I told the lady if I did my job as a Seargents Major like her department did their job, I would have lost my star and job. I wonder how many others have problems accessing HRC?
