Aetna has been giving me the run around and denied my claim

I was out on a short term disability for a Kidney pain and a Tumor. During this time I was suffering from a great deal of pain and passing of blood. I am also a Diabetic and suffer from Jorums. I was put out on a STD for a month. Aneta has been giving me the run around and denied my claim. I appealed the decision and they keep pass along the time and not giving me a straight answer or approving or denying my appeal case. They are really rude and the case managers or the supervisors can keep their story straight. My family is suffering and I still out a months pay. I feel alone fighting a Giant. My employer will not help either.
