I purchased a Groupon for the Chattanooga Ducks (boat ride) for a trip my family was taking. I purchased it two weeks in advance. When I bought the Groupon, it said to go online to the merchants website and purchase tickets with a coupon code Groupon provided. The coupon code did not work. I contacted customer service and they told me to contact the merchant. The merchant never contacted me back so I contacted Groupon customer service again and they said they would "escalate the issue" and to wait 24-48 hours for a response. I waited 72 hours and heard nothing so I contacted customer service again two days before our trip and they said they would escalate it again and to wait 24-48 hours again. I told them I didnt have that long and I wanted a refund. They said they dont give refunds once the confirmation is opened for redemption. I never got to redeem the Groupon so I paid for a useless Groupon AND paid full price for the duck boat tickets. Groupon customer service is polite but extremely USELESS and Groupon is completely USELESS. NEVER BUY FROM GROUPON. Safe your money!
