delaying a decision forcing me to keep paying them premiums for a policy I believe they never had any intention of paying.

I have been paying SunLife formerly Assurant, formerly Fortis, premiums for 20 years on a group LTD policy I converted to an individual policy. My only dislosure ever received was a certificate stating my monthly benefit was $1,000 monthly. In January 2017, after suffering my 2nd stroke in 18 mos which left me paralyzed on the left side and after living with AIDS and multiple other conditions since 1998, I finally filed a claim. They have continued to drag their feet by requesting more and more info and continually postpone making a decision. They sent me someone else’s bill, which I paid unknowingly and they applied it to another person’s policy and sent me a cancellation letter. I had to fight to get it reinstated, but I believe it’s a suspicious attempt to decline benefits. I was awarded SSDI benefits quickly; however, they keep delaying a decision forcing me to keep paying them premiums for a policy I believe they never had any intention of paying.
