Aspen Dental

My husband dental appointment for wisdom tooth extraction was forced to pay money before procedure. 111 dollars and some cents. Aspen dental called some days later saying they were cancelling on their behalf as they had over booked. I want a refund. I have gone back and forth with my credit card company. Every Time I call aspen dental they say they refunded the amount. This is a LIE. I just want a refund. They cancelled. This is unbelievable and I have gotten nowhere. Awful place.
