No results after 12 laser hair removal sessions on my bikini

I completed atleast 12 laser hair removal sessions on my bikini with them after buying 2 packages. I repeatedly told them I was seeing less results after about 4 treatments but they just kept saying I would require more treatments. I then found out at one of my last sessions that one of the ladies had turned the laser level down on multiple visits even after I told her I wasn't seeing results. I called and asked for a refund considering this information and the fact that most if don't all the hair has grown back and I now have to pay another company to get the results I already paid for. They informed me they could refund me $91 not even close to the $1200 I paid for the minimal results that were achieved.
