LivingSocial refused to refund my money after the merchant did not honor the voucher I purchased. Washington DC

I bought a $69 voucher from LivingSocial for guitar lessons. The business never honored the voucher and stopped returning emails or phone calls. When I contacted LivingSocial, they refused to refund my money. In fact, Living Social never refunds money even if the merchandise never arrives or you get stiffed on services. I cannot say strongly enough that you should not use LivingSocial. Other websites like Amazon.com and Groupon are very good about returning money when the services are bad or not received.
