I purchased a colon cleanse on Groupon then when I was about to check out your site offered me 10$ cash back on my offer but that was a catch , I have to provide and agree that theyll use my bank account for that which I am not comfortable doing that . Then they said if I dont want that I have to log on and cancel , guess what , Im not able to do it through your site . I ant this to be resolved , I dont want to be charged on my card for anything else but what I purchased. I am saving this email so I can take to my bank so I can honestly dispute with my rights . Please contact me so we can solve this
