Inappropriate conduct!! Rude, discriminatory, etc

Have you ever dealt with a case where the person is receiving LTD benefits but there have been issues with the case manager? For instance, the person was badgered about answering they felt felt completely disabled. And then, the manager said "I have people without limbs and they are working." Or, the vocational specialist looking into a person’s medical report – that was 10 months old btw – and stating " it says here you can sit for 20 minutes at a time." I wonder if I have a case against them. I was in tears. This caused a meltdown breakdown for me for several weeks. Sad thing is the vocational specialist had already spoken with me, and I said I would begin ged classes at the end of summer because of Covid. She then said "I will have to refer you back to your case manager" – basically threatening me. I reported but nobody cared nothing was done.
