Prudential continually harasses me and my family

I have been on LTD through Prudential for nine years due to a rare brain/spinal cord Disease. They continually harass me and my family with phone calls, paperwork, I have caught several videographers following me over the years. My records have always been open to them. I have complied with every request. I recently went to work doing voice overs for a local radio station. I can only do 2 hours and that is it. Then I am back into bed most days. They are now starting to harass my employer by asking for 3 full print outs of my pay-checks from Jan til now. My family and I are exhausted with this continued harrassment, even though my rare brain diagnosis has made it very clear I will NEVER be able to go back to work full time. My limit I can make per month is $900 dollars before they can deduct from my LTD paycheck and I am no where near that figure. I think $600 dollars in one month is the most I made, however, I suffered a rare brain attack from doing too much (according to my Neuro) it’s like a switch flips off. If there is ever a class action suit, please let me know.
