Cold Burn from Coolsculting

It's been two years and I finally fully recovered from the accident from cool sculpting that an aesthetician operated. During the first treatment, the machines warned about something and the lady there just said "Oh probably it is the wrong location, let me rerun this." Then after three reruns I paused the procedure and went home. I got cold burns on the abs with blisters soon after! The operator still tried to convince me to do another treatment until I said i would go to my lawyer if they didn't refund me in full. They later agreed and prescribed me pain medication and topical solutions. Not sure if the operator is still there or if the provider still has the coolsculpting qualification, but I took two years to fully recover from the discolor of the burn on my stomach.
