What do I do if Aetna says they aren't receiving my medical records?

I hurt my arm in late March of 2015. I went to the doctor and they said that I have an Olecranon elbow fracture, and that I needed to see my primary doctor for further treatment and instructions. I then called my head supervisor and told her I was calling in that Monday to see my primary due to the urgent care report. My supervisor told me that our HR rep on site said due to our policy at UPS, I couldn’t return to work until I was 100% due to their lack of light duty; And that I had to file a short term disability claim, which I did. I have been out of work since. It’s been three weeks. I’ve seen a doctor twice since then with the same diagnosis. Since then Aetna had claimed they hadnt recieved medical records, which I in turn faxed personally and am now waiting for a response. I am becomming broke. What should I do?
