SSQ Insurance Disability Insurance Reviews

I was on short-term and then long-term disability with SSQ. My doctor said she had never dealt with them before and hoped never to have again. I always sent in all requested documentation on time and then I would sit for months waiting for an answer. I had 3 different case managers who never documented anything so the new one never had a clue and would accuse me of lying and say that the previous person would never have said that. I hit the 2-year mark on long-term disability and they wanted more documents. All were sent in before the date I was told. And behold at the 2-year mark they say not only are they cutting me off but I should never have even been approved 2.5 years ago. Oh, and they want $15000 back. Excuse me? How on earth can I pay them when they cut my only source of income and I still can hardly function in day-to-day life. Now, nearly a year later I have gotten 2 requests for my doctor to fill out a medical form so my benefits can continue to be assessed?? What a joke of a company!
