Owner of Sorbet dont reply to any complaints

I have been a customer of Sorbet for more than 7 years. Two weeks back I booked for a specific treatment - no skin analysis was done and none of the treatments I requested. The cost was well over R620. I have tried calling the owner many times , cellphone goes immediately to voicemail and no messages were attended to. Left messages at the store also with no results. Why do they ripoff people in this manner. Guess they didn't know I am a model agent and this wont go down well with my models which I all refer to various branches in Gauteng. What a pity that one branch damaged the reputation of the other branches taking pride in their work. Im sure i will get an immediate response after this report to cover up. It looks like PLacecol is next on our list maybe change is as good as a holiday as they say.
