I initially filed in March and received the first 3 payments on time. Now every time I file it says unresolved issues. A claims investigator finally contacted me in June and got the back payments released then filed the next week and the same issue. It is now September and the last payment I received was at the end of June. Called the help center several times ( what a joke they are) was told the case would be expedited- after 2 weeks nothing changed called back again and was told it was never expedited. Also was told a claims investigator was not assigned even though I spoke with one that fixed it the first time around.
