New York Life has not paid me a dime in months

I work for a large company – and they have NY Life for both their long term and short term disability benefits. I have been off on STD since 6/7/17 – and NY Life has not paid me a dime. Last check was that it was in review – that was a week ago. I was originally off due to low back and leg pain – it got worse – now walking with a cane – now it has been found that I will need a total hip replacement due to my rt hip-severe arthritic degeneration with a collapsed femoral head. Also, New York Life keeps sending me paperwork, which I complete = calls me – usually at 8 am – I try to call back, and the agent does not call back. My orthopedic surgeon advised against a return to work – stating that it may not worsen the condition, but it would be extremely painful and uncomfortable. At this point, I may have to return to work since I cannot go on raiding my IRA to pay bills.
