I was charged over $1200 for a service from a dentist I never received. The dentist wrote a letter specifically saying in black and white he never did the service . After 50 days and 3 times I was told the check was sent back to me as a payback , im still told its in dispute. I told them nobody is disputing after they read the letter from dentist. Ive call over 20 times only to reach Columbia- El- Salvador . There is no corporate US number . What a disgrace this company is .
