Severe swelling with welts - left a scar on my lower face

I had lower face Ultherapy done at Ideal Image and experienced severe swelling with welts on my face. I called them and they said it probably just means I’ll have really good results. 3 months later, after everything finally healed, one of the welts left a HOLE IN MY FACE. I contacted the manager and asked how it can be corrected. She asked me to come in for photos and said she would send the info to the medical director for review. We emailed back and forth about 8 times over 3 months and she stopped returning my calls and e-mails. End result: I paid $1,400 for a scar on my face. They gave me the run around and then they completely blew me off. I went to them to improve my appearance and now I look worse than when I started AND I'm out $1,400. It’s criminal.
