An Update:
I think that calling my character and ethics into question and insinuating that I am a liar is a terrible way to provide recompense to a dissatisfied customer. I was originally disappointed with my experience and now after reading the comment on my review which was provided by by the company I am furious. I am an actual consumer who went to an actual class. I attended the Wine Love painting class on 06/12/15. I sat at the table closest to the entry way door with my four other friends at the end of the aisle that was closest to the door and I even think I wore a green shirt. I would be happy to dig up the pictures from that night for the company should they deem it necessary to believe that I had a bad experience. I waited until now to write this review and speak my mind because I didn't want to write a review when I was angry, humiliated and frustrated. 6 months later I am still disappointed and so I wrote this review. It is also infuriating to see other people on yelp have had the same difficulties with the coupons as I have and the business owner was apologetic to those consumers. However, with me she accuses me of being a competitor and just trying to make her company look bad. Of course on the off chance that I am a real human being who was an actual consumer I should do the work to call them and offer them the opportunity to make it right.
As for the coupon, I am aware that many businesses require a coupon to be presented at the time of purchase. However, I made my purchase transaction online and an innumerable amount of companies offer coupon codes specifically to be used online at the time of purchase without the need to present a physical coupon. I have often made purchases online for products that needed to be physically picked up from the store and not once have I had to show a physical coupon to pick up my product. It is not unreasonable for me to think your company might offer the same type of discounts in this digital age. Suggesting in a "rude" (this was your word) manner that I don't know how coupons work when I have been a consumer for more that 25 years is unreasonable. For that matter, I have actually forgotten my coupons in the car at two physical stores and the manager of the store actually honored the discount though their policy generally requires the physical coupon to be turned in. That happened at Lowes and Kmart, in case you are curious. There are lots of companies that value customer satisfaction and understand that a happy customer will return and spend more of their hard earned money. Spending any more of my hard earned money is not something that I will do with this company again. I hope the $10 and your stick to your rules attitude with no regard to a consumers experience was worth losing my business and that of everyone I know.
