Purchased a groupon for $99 teeth whitening for my husband and I. We went to have our teeth "whitened" and neither of us had any visible results. We contacted the office with our dissatisfaction and were told to come back in for a "complementary" whitening. The morning of our scheduled appointment, we were called and informed that the second attempt at "whitening" would in fact not be complementary as promised and informed we would be charged again. Extremely unprofessional to not stand behind your commitment to an unsatisfied client. This is obviously a scam as neither of us had any results and they tried to collect a second time after offering to make it right. Buyer BEWARE!
