I purchased 4 Groupons for bowling at Strike 10 in Deer Park, NY and when I got there 1.5 hours later I was told I couldn't use them that weekend. I contacted Groupon and requested a refund and they gave me a ton of BS and very nice language told me to screw myself. I went and read reviews of this bowling alley and of course horrible reviews and match my experience. Groupon should be vetting these lousy merchants better and when there is a problem like this they should be actually handling it instead of patronizing me throughout the entire conversation. Terrible customer service, stay away from using Groupon, the aggravation is not worth the discount.
