After $5,000 (USD) worth of dental work from Dr. Don, around 2008, I couldn't chew anything. He was the nicest guy, like your best friend (think Velvet Glove). Then was introduced to a dentist in Chapala, who looked in my mouth for 1 minute and said, "I can't fix this, but I know who can", and I was introduced to Dr. Eloy Barrangan.
Eloy worked out a repair plan, and I confronted Dr. Don in a gentlemanly fashion. He told me he'd refund my money, he just needed to meet with his accountant... Good thing I didn't hold my breath. Mutilple additional contacts, NO refund.
It cost more than $6,000 additional (USD) to get it all fixed.
He doesn't get my recommendation either...
