I hired what I was told was legitimate moving co. destroyed furniture and dumped my whole truck on sidewalk.Broken and damaged items furniture. Help

I found Hallelujah movers on Groupon. Told levitate professional movers. Have witnesses- guy could hardly drive uhaul, not moving van. Should have known then. My neighbors saw they were taking breaks more than moving. I helped move boxes down in front of truck to speed along just small items. I had spinal reconstruction two yrs ago and still have problems but it wasn't getting done, so I had to work. They were almost three hrs late without calling me. When they were done finally, as soon as we arrived in front of new apt. Opened back of truck and stuff wasn't even protected or wrapped. Took expensive oversized mirror out and destroyed. Furniture beaten up and leg broke off dresser. Many damages. When I called owner and asked about insurance he told me quote" it was already broke before went on truck. My neighbor saw it sitting outside truck before they put it in. It was definitely not broken. I was very angry at that response but it got worse. They dumped my belongings on the street.
