Take care of scamming dentists

More than a half year ago, i was so desperate and went to an dentist who is offering special mouth guards. He offered me a moth guard for 1.500 Euro and said it will be 1000% better. I paid the money, talked to a lot of other dentists and they told me that his moth guard is pure shit... sorry for my words. Now i'm not only fighting with my symptomps but also try to get my money back, together with a lawyer. Outside there are a lot of people who would take our money, just to make us some hope!
