This people are horrible. Someone steps into my office to sell cleaning and whitening appointments for $60, wearing dental assistant clothes. I bought it from him in good faith and when I go to the clinic,"THERE ARE TONS OF OTHER HIDDEN THINGS" I was told I could get cleaning for $60, Fair and Simple! Nobody took a look at my teeth before selling it to me. Now, the office manager says "No, your teeth needs more than basic cleaning, Pay extra." Couldn't they have just told that while selling it. If you take my advise, "IT'S A BIG NO"
