Picture Me Studios Never Provided Photos after Collecting Fee. Won't Answer Calls or Emails , Internet

My family and I went to Wal-Mart to have a Family Christmas Portrait done for an advertised $9.95. The pictures were taken, proofed on site, and paid for. We received a call a week later stating the pictures were ready for pickup. We went back to Walmart only to find the studio unmanned. This happened numerous ocassions. We went in again and the studio had closed and all the photography equipment had been removed.  I have attempted to contact the company by telephone and via email, all to no avail. I am never able to get to a live person on the phone, even after an hour of hold time when the computer stated the hold time was 5 minutes. No one returns the emails either. I'd like the pictures. It was our first and only family portrait.
