Pushy, rude and not honest

I bought a voucher for 4 cellulite reduction treatments on LivingSocialDeals but when I went to a so called 'assessment' I was told I have to pay 700$ more if I want to see any results and when I refused (inspite aggresive tactics) I can only use it for a facial or one treatment of hair removal. I ended up paying 100$ for one hair rem treatment in which nothing was done; I had hair removal session and know the difference but they lied to me that is normal for the hair to come back for a while!!!???They are misleading clients with fake promotions/vouchers.
